Impact of Bt Cotton in China [PDF]
World Development, 2001 Abstract A sample of 283 cotton farmers in Northern China was surveyed in December 1999. Farmers that used cotton engineered to produce the Bacillus thuringiensis (Bt) toxin substantially reduced the use of pesticide without reducing the output/ha or quality of cotton. This resulted in substantial economic benefits for small farmers.

Bt corn and Bt cotton: Valuable tools for IPM
Crops & Soils, 2017The widespread implementation of Bt crops has decreased insecticide use and increased crop yields, but it must be used in an integrated pest management (IPM) approach to protect the crop from pest species that are not susceptible to the Bt toxin and to manage resistance to preserve this valuable technology.

Nature and Performance of Bt Cotton vs. Non-Bt Cotton Across the States
2016In Andhra Pradesh, cotton is a very important crop and stands at the third place in terms of area cultivated. Over the past two and half decades there had been a significant increase in the area under cotton in the state. Cotton has been grown under both irrigated and unirrigated conditions and the latter dominates.

Cotton bollworm resistance to Bt transgenic cotton: A case analysis
Science China Life Sciences, 2010Cotton bollworm (Helicoverpa armigera) is one of the most serious insect pests of cotton. Transgenic cotton expressing Cry toxins derived from a soil bacterium, Bacillus thuringiensis (Bt), has been produced to target this pest. Bt cotton has been widely planted around the world, and this has resulted in efficient control of bollworm populations with ...

Since cotton producers do not own legal rights to kill insect populations that are susceptible to insecticides, individual producers may have no incentive to account for future, insecticide-resistance productivity losses arising from their pest-management decisions.

Prospects for BT Cotton In Mozambique
2009Mozambique’s cotton sector is very important to the economy and to poverty reduction in the rural sector. Cotton production in Mozambique is characterized by low levels of productivity, low prices and low returns. Cotton farmers in Mozambique are often no better off than their neighbors who do not grow cotton. Not surprisingly, many cotton farmers have

The Impact of Bt Cotton in China
2003Genetically modified (GM) plants are the center of an increasingly rancorous debate about the value of agricultural biotechnology. The champions of agricultural biotechnology see it as a tool to help solve problems related to hunger and excessive pesticide use (BIO 2001).
