Prevention of white braided insects is very important for good yield of groundnut.

Published on: 29-Aug-2023

Farmers expect a decent harvest from groundnut planting when they can eliminate white braid disease in groundnut crops. Whiteflies are omnivorous insects that live on the soil.These are also referred to as root braids. Let us inform you that white braided insects feed on organic substances found in soil and plant roots. Aside from groundnuts, white braided potatoes, walnuts, tobacco, and other oilseeds, pulses, and vegetable crops obtain their sustenance by attacking the roots of guava, sugarcane, coconut, and betel nuts. Whiteflies can cause a 20-80% loss in the groundnut crop.

When does the incidence of whiteflies peak?

Normally, white threads are visible all year. However, their activity becomes more obvious during the wet season. Adult males congregate in huge numbers for mating during the first monsoon rains in mid-May or June. Females found in and near the fields return to the earth in the early morning. Also, they begin to lay eggs. They then return to the soil to complete their life cycle. The earth remains inert at a depth of roughly one metre until the monsoon rains arrive.

Symptoms of white-braided infection in groundnut field

Because this insect lives underground, the damage it does is often overlooked. Infected plants seem yellow and wilted. In such a case, the plant ultimately dries out and may be readily removed from the ground. Plants perish with strong infestations. Also, dead plants appear in spots throughout the fields. Whiteflies also consume plant roots, destroying them. Braids cause a significant loss in groundnut productivity. Adult moths are the first to create holes in leaves at night. They then consume the whole leaf with the exception of the middle leaf's central vein.

White braided pest control in a groundnut crop.

Let us inform you that if a whitefly infestation occurs in any location, it cannot be managed by a single farmer. To do this, the farmer brothers as a society must take preventive actions. White hair management is only attainable through a community-based approach.

White Braided Adult Management

After the first rain, use one light trap per acre.

Cut down trees near fields in flood-prone locations. Also, trim and remove the shrubs around the field.

Spray pesticides such as Imidacloprid 17.8 SL @ 1.5 ml/lit or Monocrotophos 36 SL @ 1.6 ml/litre on trees and shrubs at sunset.

Gather fallen strands near the trees and dispose of them.

White Braided Pest Management

If water is available, sow early.

Farmer brothers should utilise better-decomposed organic manure.

Farmer brothers should undertake thorough ploughing in the summer to expose the pupae to direct sunlight.

Pay extra attention to preserving tiny birds, which feed on these whitetails.

Before planting, incorporate carbofuran 3 cg @ 33.0 kg/hectare or phorate 10 cg @ 25.0 kg/hectare into the soil.

Spraying pesticides such as Thiamethoxam 25 WS @ 1.9 litres/ha or Fipronil 5 FS @ 2.0 litres/ha along the sowing lines in whitefly-infested fields. Use.

Before planting, treat seeds with Chlorpyrifos 20 EC at 6.5-12.0 ml/kg or Imidacloprid 17.8 SL at 2.0 ml/kg.

When adult whiteflies are detected in the crops, spray Chlorpyrifos 20 EC @ 4.0 litres/hectare or Quinalphos 25 EC @ 3.2% litres/hectare in the roots of the crops.
