Validation of recommended doses of insecticides against sucking pests of BT cotton
TLDR
Higher doses performed better than the recommended doses indicating possibility of resistance in sucking pests of Bt cotton.Abstract:
Comparative efficacy of acetamiprid, imidacloprid and dimethoate at university recommended dose, double the recommended dose and dose used by the farmers was evaluated against sucking pests of Bt cotton. The results revealed that minimum population of sucking pests was observed in dose of acetamiprid used by farmers (6.0 g/10 L of water) and was followed by double the recommended dose of imidacloprid (4.5 ml/10 L of water) and higher dose of dimethoate used by farmers (30 ml/10 L of water). Maximum seed cotton yield (1816.81 kg/ha) was recorded in higher dose of acetamiprid used by farmers @ 6 g/10 L of water and it was at par with imidacloprid @ 9 ml/ 10 L of water (1661.00 kg/ha) and imidacloprid @ 4.5 ml/ 10 L of water, double the recommended dose (1453.00 kg/ha). However, maximum ICBR (1:13.7) was obtained in acetamiprid @ 6 g/10 L of water (higher dose used by farmers) and was followed by acetamiprid @ 3 g/10 L of water (double the recommended dose) with ICBR of 1:9.8. Higher doses performed better than the recommended doses indicating possibility of resistance in sucking pests of Bt cotton.read more

Fertilizers, BT technology, and insecticides contributed to 60%, 23%, and 17%, respectively to the increase in BT cotton yield: An analysis from 2000 to 2014 in India
TL;DR: Three strategies namely drip fertigation, intercrossing Bt and non-Bt hybrids for resistance management in bollworms, and IPM for sucking pests will primarily drive the research priorities and policy actions for the next 5 to 10 years in sustaining the economic benefits of the six million cotton farmers in India.

Monitoring of Insecticides Resistance in Field Populations of Helicoverpa armigera (Hub.)(Lepidoptera: Noctuidae)
TL;DR: Pair wise comparison of the log LC50 of insecticides against all populations showed a correlation between the various insecticides, suggesting cross resistance was occurring, and emmamectin benzoate and lufenuron were significantly more toxic than other tested insecticides.
