Aphid In Crop
About the Practice
Aphids attack the standing crop, vegetable plants and vines. It damages leaves, flowers and stem of the plant and gets the food gradually by sucking the sap. It remain stuck to the plant, damages the crop and thus plant becomes unproductive. As informed by farmer, 4 kg of tinospora (Tinospora cordifolia) is boiled in 8 L of water. It is boiled till half of mixture remains in the container. Thereafter, this mixture is strained and 15 ml is filled in 15 L capacity pump. This mixture is sprayed on the aphid infested crop to protect. It is a self-developed practice.

Practice Details
Formulation: Liquid solution of 4 kg of tinospora (Tinospora cordifolia) is boiled in 8 L of water.
Ingredients: Tinospora (Tinospora cordifolia), water
PAS 1:
"Tinospora cordifolia is a good reservoir of bacterial endophytes which have the capability to produce similar or different metabolites as produced by host plant and can be applied to wide range of areas like medicine, agriculture and industry."

"Growth Regulatory Activities of Different Extracts of Tinospora Cordifolia on Some Vegetable Seeds with their Chemical Investigation - An experiment was conducted to investigate the growth regulatory activities of different extracts of Tinospora cordifolia on radish (Raphanus sativus), swamp cabbage (Impoea aquatica) and ladys finger (Hibiscus esculentus) with the attempt for chemical investigation of effective plant extract. The chloroform extract of Tinospora cordifolia significantly increased and enhanced germination, growth of shoot length and root length of radish and ladys finger whereas and delayed germination, growth of shoot length and root length of swamp cabbage seeds compared with control. In the same way, ethanol extract of Tinospora cordifolia significantly increased germination, growth of shoot length and root length of swamp cabbage followed by control and chloroform extract. Our study reveals that different extracts of Tinospora cordifolia contain growth regulatory active principle. Among the extracts, chloroform extract was shown better performance in terms of percent germination, growth of shoot and root length of radish and ladys finger. To find out effective compound from chloroform extract, thin layer chromatography was done and showed five distinct compounds. Further study is needed to determine structure for finding growth regulatory compound for agricultural usage."

"An estimate of the potential economic losses to some crops due to aphids in Britain - Average infestations may give a potential economic loss of £70 × 106; severe widespread infestations of wheat alone could result in losses of £120 × 106. Losses may be reduced by more accurate insecticide applications based on monitoring and forecasting."
