Practice Name:

Controlling the Attack of Green Caterpillar


Details
Category Crop Pest & Disease Management
Crop Pigeon pea
Crop Family Legumes
Scientific Name (Cajanus cajan)
Vernacular Name Toor, Arhar, Red gram
Scout HBN
Ingredients Citric acid, Kerosene and water.
Details of Innovation Farmer uses citric acid to control the caterpillar pest in the tur or pigeon pea (Cajanus cajan) crop. With the onset of pod formation in the crop, the possibility of pest attack also increases. The prominent pest of the pigeon pea plant is the green caterpillar (Heliothis spp). The farmer approximately dissolves 10 to 25 grams of citric acid in 15 liters of water. This solution is sprayed on the crop. This controls the incidence of green caterpillars without any side-effects on the crop. Alternatively, a solution of 10 milliliters of kerosene mixed in 10 liters of water can also be used as a spray to control the pests.

PAS_1 "Insecticides from Neem - Derivatives of neem (Azadirachta indica A. Juss) have traditionally been used by farmers in Asia and Africa to ward off insect pests of household, agricultural, and medical importance. Unlike ordinary insecticides based on single active ingredients, neem derivatives comprise a complex array of novel compounds which have diverse behavioral and physiological effects on insects. Repellency, feeding and oviposition deterrence, growth and reproduction inhibition, and other effects have been attributed to neem compounds - azadirachtin, salannin, meliantriol, etc. that occur mainly in the seed. However, the complexity of chemical structure of these compounds precludes their synthesis on a practical scale. Therefore, the use of simple formulations of neem derivatives such as leaf or kernel powder or extracts needs to be popularized. Their being safe to nontarget organisms, including humans, make them ideal insecticides. Several azadirachtinrich formulations have already been commercialized for use on nonfood and food crops." https://pubs.acs.org/doi/abs/10.1021/bk-1989-0387.ch009
