Grub: creamy white legless grubs, stout and distinctly curved and swollen in the middle of the body. Disc-on-stump traps consist of corn slices placed on top of harvested plants cut at the rhizome. The adults over-winter on citrus or non-crop native or exotic ornamentals, and start to move into lychee and longan orchards in spring when the trees flower. Banana stumps kept in the field after harvest must be removed and destroyed as they serve as weevil refuges and breeding sites, Blackened mass coming out from pseudostem, Pale yellow streaks on the upper surface of leaves, Centre of the spots turns to grey colour, Microscopic view of Mycospharella musicola, Apply mud slurry mixed with neem oil 5% on the pseudostem five month after planting in heavily infested areas to prevent oviposition, Closely monitor the plants for the detection of oviposition punctureszxzsxz, Spray chlorpyriphos 20 EC or quinalphos 25 EC 2ml/lit. the integrated approach of pest … The nematode enters the roots as well as corms and causes usually induce reddish brown cortical lesions which are characteristic feature of the disease. Affected plant parts - Field release of entomopathogenic fungus. Instead of Monoctophos the suckers may be dipped in clay slurry and sprinkled with Carbofuran granules at 40g/corm, Soil drenching of Carbendazim 0.2 per cent solution alternated with Propiconozole 0.1% around the pseudostem at bimonthly intervals starting from five months after planting, Application of urea + sugarcane trash (250g/pit) followed by lime (1Kg/pit) and neem cake (1-2Kg/pit), Application of neem cake @ 250 Kg/ha was most effecgtive in controlling Fusarium wilt in Rasthali cultivar. Sep08-Aug09 Rs.5.00: S.K.Manoranjitham. Before planting, the suckers should be dipped in 0.1 per cent quinalphos emulsion. Use clean planting material – This can be done by selecting vigourous healthy planting material, Hot water treatment of corms at 52 to 55°C for 15 to 27 minutes, Suckers should be pruned periodically and infested pseudostems must be removed from the field and destroyed.Â, Crop rotation with non host crops like paddy and sugarcane, Ensure proper fertilization and free from weeds at all times, Use mulch away from the banana stool leaving a clear ring about 60 cm from the base of the stool to keep the roots growing towards the surface and to avoid moist conditions near the stool, which will attract banana weevils, Do not take regular crop in the same field to avoid initial infestation, Removal of pseudo stems below ground level, Avoid growing Robusta, Karpooruvally, Malbhog, Champa and Adukkar, Grow less susceptible varieties like Poovan, Kadali, Kunnan, Poomkalli. A number of insect pests can affect banana plants. Pests. The snails, which live up to six years in favourable conditions, The infestation was found to be intense in areas with high population density. Banana Pest and Disease Management Tamil. Sun hemp and chrysanthemum should be grown 45 DAP of Banana and incorporated into the soil one month later. The banana aphid is a serious pest of banana due to its ability to transmit banana bunchy top virus (BBTV). Banana trees (Musa spp.) The young grubs after hatching in the soil headed towards the roots and start feeding on them. About 60 mg of Pseudomonas (in a capsule) can be applied in a 10 cm deep hole made in the corm. Asprothrips navsariensis is a minor pest of banana leaves. The formic acid, with a pH of 2-3, burns the tender skins of the young fingers, leaving irregularly shaped, blackened areas on the fruits that expand as the fruits expand.

These areas then develop the typical rusty-red to dark brown-black discolouration. Infested plant shows yellowing and withering of leaves, slowed plant growth, root destruction, reduced fruit production. Scales feeding on the undersides of leaves may cause yellow spots to appear on the top sides, and these spots progressively become larger as the scales continue to feed. Drench suckers 2% bleaching powder to control the disease in field at planting followed by another drenching the soil after 3rd month of planting to control the pathogen. During the advanced stages of infestation,  when split open the stem, exhibits extensive tunnelling both in the leaf sheath and in the pseudostem, Rotting occurs due to secondary infection of pathogens and a foul odour is emitted.Â. Bunches, pseudostem and the suckers should be sprayed chlorpyriphos, Soil application with Fipronil and Bifenthrin, Nymph and adult suck the plant sap and inject toxic saliva in the tissue. Collect and destruct beetles in kerosene mixed water and using light traps / pheromone traps during night hours. Areas with untreated garbage and places of water logging are their favourite spots, Crop rotation, enhancement of soil quality, choice of resistant varieities, water management, providing mechanical barriers, post harvest treatment. While the taste and texture of the fruit within these peels remains unaffected, the exterior discoloration reduces the marketability of affected fruit. The lesioning of primary roots together with girdling and death of anchoring roots leads the plant prone to ‘tip over’ under wind pressure. The above discussed subject along with the disputed pictures were sent to National Research Centre for Banana, Trichy also for re … They can give birth to 4 aphids per day with an average production of 14 offspring per female. The planting tools should be cleaned before being used in the field, Well decomposed manure should be used, Grow marigold in the inter space which serves as repellent and trap crop, Covering the field for 6 to 8 weeks with plastic after tilling and watering raises the soil temperature. Banana stumps kept in the field after harvest must be removed and destroyed as they serve as weevil refuges and breeding sites; Crop rotation with non host crops like paddy and sugarcane. TNAU Notes pdf can be easily downloaded by clicking on the below provided links. The disease incidence. Internally, symptoms first become obvious in the xylem (water conducting) vessels of the roots and the rhizome. Banana Production Technology Tamil. The disease is known to occur in all banana-growing states. Collect and destroy the affected plant parts, Spray application of monocrotophos 36 WSC 0.04%. In severe cases the skin develops longitudinal cracks and sometimes fruit may split. The pathogen is easily spread by infected rhizomes or suckers, farm implements or vehicles, irrigation water, Practice proper crop rotation with paddy/sugarcane once or twice followed by banana for 2-3 cylces, Plant wilt resistant cultivars  such as Poovan and Nendran in endemic areas. The infestation of termite is more in rabbi season. Water is required for the bacteria to invade into the plant. This app covers the topics of Insect, Nematode, Fungal, Bacterial, Viral Disease. Since scale insects may occur on all plant parts, every part of the plant must be checked. The abdomen is often darker than the head and thorax. Treat the cut end of the leaf petiole with Chlorpyriphos (2.5ml/lit) + 1 ml sticking agent, After harvesting of banana bunch cut the tree at base and treat it with 100ml Carbaryl (2g/lit) or apply 10g Beauveria bassiana, Swab the cut surface of the longitudinal split traps with 20g of Beauveria bassiana fungus or Heterorhabditis indica nematode and the weevils die on their own due to infection. Apply Chlorpyriphos 20EC @ 400 ml / gunta with irrigation water.

TNAU Agritech Portal :: Crop Protection : Crop Insect Pests. A biological control agent (a parasitoid) was originally established in Torres Strait in 1992 by DPI&F entomologists from Brisbane. Symptoms of damage. Conidiophores are cylindrical, tapered towards the apex, hyaline, septate, branched and sub-hyaline towards the base, each with a single terminal phialidic aperture. Death of unopened pipe, withering of outer leaves. Adult weevils are attracted to the cut stems or corms for shelter, to feed and to lay eggs. The emerging larvae are fleshy, yellowish  white and apodous.  The larvae feed on tissues of the succulent sheath by tunnelling extensively and may reach as far as the true stem Egg: elongate-oval, about 2 to 3 mm long and white in colour. Use mechanical barriers in the field. Yellowing of leaves and rusty growth over fruit. Predatory ants such as big headed any and Tetramonrium spp. The National Banana Extension and Development Project has produced video about tropical race 4 Panama disease (Fusarium wilt). Egg period is 4 to 36 days depending on temperature conditions. Death of unopened pipe, withering of outer leaves. When the true stem and peduncle are tunnelled after flowering, the fruits do not develop properly, presenting a dehydrated condition with premature ripening of the bunch itself. The spread of the disease is by air-borne conidia and numerous insects which frequently visit banana flowers also spread the diseaseÂ, The disease is favoured by high atmospheric temperature and humidity, wounds and brusies caused in the fruit and susceptibility of the variety, Practice crop rotation with paddy or sugarcane, Keep the field free of weeds and provide good drainage, Fruit should be free from infection and as possible before it is transported, stored and ripened. Virus is disseminated by suckers and Aphis gossypi. TNAU Agritech portal is no exception and the mistakes pointed out by this blogger was corrected in their website immediately (within 12 hours). The front margin of the wings is made up of a fringe of black hairs and, when at rest, these give the adult thrips a characteristic longitudinal black stripe down the middle of the abdomen. They are endoparasites. Traditional pest and disease identifica - Removal and destruction of affected leaves. Adults are reddish-yellow and with a long slender body measuring approximately 1/6 inch in length. The adult weevils are black-coloured and measure 23-39 mm. Natural enemies - Predatory ants such as the bigheaded ant (Pheidole megacephala) and Tetramorium spp  feed the eggs, grubs and pupae of weevils. In later stage the whole seedling withers. The causal organism of nematode is Burrowing nematode (Radopholus similis), Root lesion nematode (Pratylenchus coffeae), Root knot nematode ( Meloidogyne incognita), Sprial nematode(Helicotylenchus multicinctus) Application of bio control agents like Trichoderma viride @ 25 g for 4 times once at the time of planting in the planting pit and remaining doses at third, fifth and seventh month after planting, Application of T.harzianum Th-10, as dried banana leaf formulation @ 10g/platn in basal + top dressing on 2,4,and 6 months after planting, Dipping the planting materials in spore suspension of P.fluorescens at 10g per plant at 3,5 and 7 months after planting, Machinery and equipment should be treated with a  sanitary solution such as Farmcleanse®.

The nymphs and adults congregate under the outer base of the pseudostem, Aphids always accompanied by ants, which act as dispersing agents of nymph, Honey dew secretion appears on the plants which attracts the ants, The aphids suck the sap of the plant and reduce the growth and vigour, They also act as a vector of Banana Bunchy Top Virus (BBTV). Avoid susceptible varieties such as Rasthali, Monthan, Karpuravalli, Kadali, Rasakadali, Pachanadan etc. The development of feeder roots is affected in case of high population of nematodes in the soil. Use of well decomposed organic manure. Then they bore into the pseudostem base and rhizome/corm, but also into the base of suckers and into roots. CO-PI: 68: Standardization of mat system of cultivation for continous harvest of banana Cv.Grand Naine: TNAU-NADP-Precision farming One year. As symptoms progress into the pseudo-stem, continuous lines of discolouration are evident when the plant is cut longitudinally. In field the disease spread mainly through suckers, The diseased plants should be removed as and when noticed to avoid the spread of the disease, Disease free planting materials should be used for new planting, The banana gardens should be kept free from weeds, Weeds in the nearby areas should be removed as the virus survives in them in off-season, Early detection by regular inspection of planting and eradication of diseased plants from the field as soon as they are noticed.               Scales cause damage by sucking the juices from the plants. It is known from India (Gujarat and Tamil Nadu) and Indonesia (Bogor).

The infested fruits fetch low market value in case of severe scarring of the fruit skin. Steinerma and Heterorhabditis sp of nematodes attack both adult and grubs in the field. Bunch covers (which cover the full length of the bunch) do provide some protection if applied very early. Apply castor cake 250g or carbaryl 50g dust or phorate 10g per pit before planting also prevents infestation. Remove infected plants immediately. It nests in burrows, gulches, rock piles, rock walls, wastelands, fields, and embankments.  It causes great damage to sugarcane, banana, pineapple, coconuts, coffee, and other fruit and vegetable crops. Pupation takes place in holes bored by the grubs. Use of salt to kill the pest as it alters the soil pH, The application of salt will become untenable during rainy days, The meat of the snails thus killed will rot with foul smell, Release predators  like predatory snail (Euglandina rosea), flatworms (Platydemus manokwari) and  pathogens in the field,  Metal salt-based molluscicides as snail baits and snail pellets. Tingid or Lace wing bug: Stephanitis typicus. Plants are easily blown down by mild to strong winds. Nematode causes reddish-brown to black,elongated lesions which are readily seen when the roots are split open. If the scales are not controlled, leaves will drop prematurely, sometimes killing portions of twigs and branches. All these problems contributed to a new way of thinking concerning pest control practices, i.e. Remove the pseudostem after harvest and treat it with Carboryl (1g/lit) or Chlorpyriphos (2.5ml/lit). Dip the suckers in Monocrotophos solution (14 ml in 1 lit water) for about 20 minutes to kill the eggs and grubs of the corm weevil . 1 kg neem cake, 200 gm nitrogen, 40 gm phosphorus, 200 gm potassium per plant, 4 weeding at 2 months interval up to 8 months stage, Spraying Methyl Demeton 0.03 per cent (0.3 ml/lit of water) at 3 to 4 weeks interval controls the vector and reduces the spread of the disease, Foliar spray of micronutrient (0.2% CuSo4(2ml/lit), 0.2% FeSo4(2ml/lit), 0.5% ZnSo4(5 ml/lit) and 0.1% H3Bo3(1 ml/lit of water) at 3,5 and 7th month after planting and spraying Glyphosate 2Kg per hectare to control weeds, Control of insect vector by spraying Phosphomidon at 1 ml per litre or methyl demeton at 2 ml per litre or monocrtophos at 1ml per litre. Egg: Eggs are not visible to the naked eye. Occurrence if black lesions on the pedicel causes withering of the pedicel and dropping of the fingers from the hands, Sometimes the main stalk of the bunch may become diseased. Disc-on-stump traps consist of corm slices placed on top of harvested plants cut at the rhizome. White Grub are mainly observed during rainy season in nursery. Grub period is 20 to 25 days Be sure plants are free of scales before they are placed in the production area of the nursery. Control. Leaves are bunched into a rosette appearance, stunted growth and leaf margins are wavy with upward rolling. They are active at night. Grub: Application of over 100 g or neem oil was phytotoxic (harmful to plants) and uneconomical. Roots eventually blacken and die. This pathogen contains colonies of white to purple pigemented mycelium. Fore wing - Stout moth with wavy white markings on the brown. Symptoms of damage. Meloidogyne spp. Snails begin laying eggs at six months of age and fecundity lasts approximately 400 days. Collect and destroy egg masses and caterpillars, Use burning torch to kill the congregating larvae, Use light trap to attract and kill the adults, Young larvae feed by scrapping the leaves from ventral surface. They cause rotting of the corms and act as a vector to the fungus Fusarium oxysporum. Yellow and purplish spots in the sub marginal areas. The weevils can be collected by hand and destroyed. Infestation of the weevil normally starts in 5 month old plants. Though occasionally large populations are seen, economic damage is negligible. The nose is roundly pointed, ears rather short, eyes medium size, hind feet dark on underside.  Females have four pairs of nipples. The virions are flexuous filamentous, The virus is transmitted through aphid vectors such as Aphis goosypii, Pentolonia nigronervasa and Rhopalosiphum maidis. View full-text.

Fore wing - Stout moth with wavy white markings on the brown. Exudation of plant sap – initial symptom, Blackened mass comes out from the bore holeÂ, Tunneled part decomposes and pseudostem becomes weak, Remove dried leaves periodically and keep the field clean, Use healthy and pest free suckers to check the pest incidence, Do not dump infested materials into manure pit, Uproot infested trees, chop into pieces and burn, Use longitudinally split pseudostem trap at 65/ha, Dilute 50 ml of monocrotophos 36 SL with 500 ml of water and inject 4ml in the pseudostem, 2ml at 45 cm from ground level; another  2m at 150 cm from ground level, Leaves are bunched into a rosette appearance, Leaf margins are wavy and upward rolling             Â, Seen in colonies on leaf axils and pseudostem, Use healthy and pest free suckers to check the pest incidence  Â, Spray methyl demeton 25 EC 0.05% or monocrotophos 36 SL 0.072%, Direct the spray towards the crown and pseudostem base upto ground level, Inject monocrotophos 36 SL 1ml/plant (1ml diluted in 4 ml of water), Avoid injection of monocrotophos after flowering, Collect and destroy the damaged leaves, flowers and fruits along with life stages, Spraying with dimethoate 30 EC - 850 ml/ha or phosphamidon 85 WSC - 300 ml/ha, Spray methyl demeton 25 EC 2ml/lit or monocrotophos 36 WSC 1ml/lit, Spray carbendazim 3g/ litre of water Application of press mud at 5 kg per tree reduces the wilt incidence, Collect and destroy the affected plant parts, Spray application of monocrotophos 36 WSC 0.04%, Field release of coccinelid predators likeÂ, Rusty reddish discolouration on the fingers. Dipping the suckers in 20% neem seed solution at planting. Without its natural predators it has assumed major pest status.                 Spiraling whitefly adults are small (2.0mm long), white and moth-like in appearance and mode of flight. Celphos (aluminium phosphide tablets), especially during In case of severe infestation spray as in case of stem borer. Early symptoms of the infestation are the presence of small pinhead-sized holes on the stem, Fibrous extrusions from bases of leaf petioles. Not a fly at all, but a relative of the bugs, spiraling whitefly derives its name from the characteristic egg spirals that the adult whitefly lays on foliage and fruit. A single sac contains several hundred eggs. Deep ploughing of field is a good practice. Such plants are readily blown over and the roots are exposed.
