Control measures of thrips in watermelon

The nymph and adult thrips insect, suck the cell sap by scraping the leaves of watermelon plants, on the soft stalk, buds and flowers of the plant, it becomes curly because of thrips infestation. Due to its effect, the plants remain stunted.
To control thrips, spray Lambda Cyhalothrin 4.9% CS @ 200 ml/acre or Profenophos 50% EC @ 500 ml/acre or Fipronil 5% SC @ 400 ml/acre at 15 days interval.
Use the pesticide at an interval of 15 days.

Aphids are small, soft-bodied small insects that can be yellow, brown, green, or black.
They usually suck the sap from the plant by forming groups on the corners of small leaves and twigs and secrete sticky substance (honeydew), which increases the chances of fungal diseases.
Leaves and twigs may wither or become yellow due to severe infestation.
Spraying of Thiamethoxam 25% WG @ 100 gram/acre or Imidacloprid 17.8 %SL @ 100 ml/acre or Flonicamid 50% WG @ 60 gram/ acre to protect against aphid.
Use Beauveria Bassiana @ 250 gram/acre as biological treatment.

The onion’s maggot is a very small white colored insect
It affects the onion tuber
In large tubers, 9 to 10 maggots attack and make it hollow.
Because of which the onion tubers rot completely
To prevent this pest, use Fipronil 0.3% 7.5 kg/acre or cartap hydrochloride 7.5 kg / acre as a soil treatment.
Fenpropathrin10% EC @ 400 ml/acre or Chlorpyriphos 20% EC @ 1 liter/acre.
Spraying Beauveria Bassiana @ 250 gram/acre as a biological treatment.

Nymphs and adults suck the cell sap from the leaves.
The affected leaves curl and dry.
The affected plants show stunted growth.
Whiteflies are also responsible for transmitting yellow vein mosaic virus or leaf curl disease.
4-5 foliar spray of dimethoate 30% EC @ 300 ml/acre or profenophos 50% EC @ 400 ml/acre at 10 days intervals.

Due to the change in the weather, many types of pests can attack crops because the moist environment condition is suitable for it.
There is a possibility of attack of Red Beetle insect in Summer Cucurbits vegetables, if the large number of this insect then spraying of Cypermethrin 4% EC + Profenophos 40% EC 400 ml or Bifenthrin 10% EC 200 ml or Dichlorovos 76 EC 300 ml / acre.
Spraying Thiamethoxam 25 WG 5 gm/ 15 liters of water in the okra to control the sucking insect such as white fly, aphid, jassid etc.
There is a high possibility of Thrips in Onion crop so spraying Profenophos 50 EC @ 45 ml or Lambda cyhalothrin 4.9% CS @ 20 ml or Spinosed @ 10 ml or Fipronil 5 SC @ 15 liters water per acre.
Use 0.5 ml mixture with insecticide in 15 liters of water, so that the insecticide is absorbed by the plants properly.

The population of Pulse beetle has been observed rapidly after 60 days of stored granular storage period.
Due to the initial loss due to transplantation of beetle in gram, 87.23% seed damage and 37.15% weight loss were observed within 120 days of storage.
In various oils and plant products tested, Neem and castor oil @ 6 ml/kg seed proved effective for four months of storage.
Coat the seed with small quantities of vegetable oil or mix neem leaves in the stored grain.
Dip jute bag in 10% Malathion solution.
use airtight storage structure.
Fumigation with aluminum phosphide protects the seed without affecting the viability.

This insect is active from November to February.
Damage is more in rainfed and late sown crop.
Yellowing of young plants is observed due to root aphids. In this case minute yellowish brown aphids may be present near the base or on the roots of the plant.
Aphids also vector a viral disease named barley yellow dwarf virus (BYD). Yield of infected wheat plants can be reduced by 50%.

Control-

Avoid late sowing.
Avoid use excess nitrogen fertilizers.
If the infestation in standing crop, Spray imidacloprid 17.8% SL @ 60-70 ml/acre.
Or apply thiamethoxam 25% WG @ 100 gm/acre in soil with fertilizer/Sand/soil before irrigation.

Yellow Mosaic Disease in Okra/Bhindi:-

This is the most important and destructive viral disease in bhindi.
The disease infects at all the stages of crop growth and severely reduces growth and yield.
The disease is transmitted by whitefly.
The characteristic symptoms of the disease are a homogenous interwoven network of yellow veins enclosing islands of green tissues.
Initially, infected leaves exhibit only yellow coloured veins but in the later stages, the entire leaf turns completely yellow.
The fruits of the infected plants exhibit pale yellow colour, deformed, small and tough in texture.

Control-

Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread.
Parbhani Kranti, Janardhan, Haritha, Arka Anamika and Arka Abhay can tolerate yellow vein mosaic.
Do not use high fertilizer during plant growth.
Do not roted okra with other hosts of virus.
If possible, choose early planting to the controlling of yellow mosaic virus disease.
Keep sanitation while using any tools that are using in crop.
Use 4-5 sticky trap/acre to the controlling of whitefly infestation.
Spray imidacloprid 17.8% SL 80 ml/acre for the controlling of whitefly.
Spray dimethoate 30% EC 250 ml/acre of water.

Management of Termites in Wheat:-

Termites damage the crop soon after sowing and sometimes near maturity.
They feed on roots, stems of growing plants, even dead tissues of plant feeding on cellulose.
The damaged plants dry up completely and are easily pulled out.
The plants damaged at later stages give rise to white ears.
Infestation is heavy under unirrigated conditions and in the fields where un-decomposed farmyard manure is applied before sowing.

Management –

Apply deep ploughing before sowing.
Use well rotten FYM in field.
Fill kerosine in mound of termite.
The seed should be treated with Chlorpyriphos (20% EC) @ 5 ml/kg of seed before sowing.
Broadcast Chlorpyriphos (20% EC)@ 1 litre/Acre with any fertilizer.
