Avoid mattacking (leaving the plant after bunch harvest for recycling of nutrients) in weevil endemic areas. Fore wing - Stout moth with wavy white markings on the brown. About 60 mg of Pseudomonas (in a capsule) can be applied in a 10 cm deep hole made in the corm. Do not produce bunches. Control of insect vector by spraying Phosphomidon at 1 ml per litre or Methyl Demeton at 2 ml per litre or Monocrotophos at 1ml per litre . Use Longitudinal Split Pseudostem Traps (LPST) – This traps (45cm long) are made from the pseudostem pieces cut longitudinally in two halves. Spray Copper oxychloride or Zineb with gas oil or mobile oil or white oil. Hind wings - white having a brown patch along the margin. Spray applications should be timed to coincide with the crawler stage which is most susceptible to insectisides. This parasitoid is a small, almost microscopic orange-coloured wasp that is host specific to the pest and has already successfully controlled pest populations in Torres Strait and Cape York Peninsula. These turn a reddish-brown to maroon colour as the fungus grows through the tissues. Initially, dark green streaks appears in the veins of lower portion of the leaf midrib and the leaf stem. Remove the pseudostem after harvest and treat it with Carboryl (1g/lit) or Chlorpyriphos (2.5ml/lit). Adults start producing young one day after reaching maturity. The incubation period ranges from  3 to 8 days.Â. 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, Trap adult weevils with pseudostem chopped into small pieces. Injection should not be given after flowering. Grub: Though occasionally large populations are seen, economic damage is negligible. Provide proper drainage and avoid water logging in the fields which favours infection. Larva - Pale greenish brown with dark marking. Weevils may live for up to two years, and can live without food for six months, but are very sensitive to desiccation and will die within 48 hours if kept in a dry substrate. Scales cannot fly; therefore they do not readily infest plants as do most other insects. Egg period is 4 to 36 days depending on temperature conditions. Collect and destroy egg masses and caterpillars, Use burning torch to kill the congregating larvae, Use light trap to attract and kill the adults, Spray chlorpyriphos 20 EC or quinalphos 25 EC 2ml/lit, Young larvae feed by scrapping the leaves from ventral surface. This insect sometimes live in the heart of the pseudostem within the roll of the central leaf.             Scales, especially armored scales are very difficult to control when mature. Heavily infested plants soon develop a black sooty appearance from mould growing on the sugary secretions that the whitefly immatures excrete. The above discussed subject along with the disputed pictures were sent to National Research Centre for Banana, Trichy also for re … Nymphs – are yellow colour, occur in under surface, Adult – yellow colour with minute fringed wings, seen in under surface of leaves, 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.

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. Banana aphid populations are often tended by ant species. The virus has multi component genome, There are six circular single stranded genomes known to be established, The virus concentration is more present in phloem, It is transmitted by infected suckers and banana aphid, Remove and rouging of infected banana plants, Chop,dry and bury the infected plants, Maintain clean, weed free field for early detection of infested suckers, Avoid banana cultivation in sugarcane and cucurbitaceous areas as sugarcane mosaic virus or cucurbit mosaic virus can easily spread to banana, The diseased trees should be injected with 4 ml of Fernoxone  solution(50g in 400 ml of water), Insertion of Fernoxone capsules (containing 200 to 400 mg of chemical per capsule) into the pseudostem by using the banana injector or capsule applicator, The pathogen affects even the immature fruits. The disturbed ants eject formic acid from their abdomens as a defense reaction. Use healthy and pest free suckers co check the pest incicence, Ratoon and inter crops shoul not be taken up, Collect planting material from healthy plants. Hank pick and destroy the caterpillar, Collect and destroy the damaged plant parts, Summer ploughing to expose to the pupae, Spray application of azinphosethyl, chlorphyriphos and monocrotophos, Severe infestation – spot application of Bt, The adult beetles feed on the tender leaves and fruits and remain hidden under unfolded leaves. Death of unopened pipe, withering of outer leaves. They are three to 5-septate measuring 23-54 x 3-4.5 µm. These populations are generally covered in a heavy coating of white, curly 'wax' and a sugary secretion that is produced by the whitefly immatures.
