近日,巴西可持续农业科学委员会(CCAAS)成员、圣保罗州立大学农业科学学院的教授Ciro Antonio Rosolem称,对巴伊亚和马托格罗索州进行的考察发现,种植抗棉铃虫的转基因棉花最大可以使杀虫剂使用量减少12倍。Rosolem说,在本次种植季,巴西多个地方扩大转基因作物种植面积的主要原因是棉铃虫的大暴发。农民反馈如果不采用转基因技术,几乎无法种植棉花作物。大豆和玉米的种植面积确实比棉花更多,但与此同时,大豆品种的抗性作用以及其他一些技术也正在失去效用,因此当前种植季应关注棉花作物。预计转基因棉花种植可能达到170万英
Ciro Antonio Rosolem, a member of the Brazilian Academy of Sustainable Agricultural Sciences (CCAAS) and a professor of agricultural science at State University of Sao Paulo, said recently that inspections in Bahia and Mato Grosso found that cotton bollworm was the largest Can reduce pesticide use by 12 times. Rosolem said that the main reason for expanding the area planted with genetically modified crops in various parts of Brazil during this planting season was the outbreak of the cotton bollworm. Farmers’ Feedback It is almost impossible to grow cotton crops without the use of GM technology. Soybean and maize do indeed grow more than cotton, but in the meantime, the resistance of soybean varieties and other technologies are also losing their effect, so the current crop season should focus on cotton crops. GM cotton planting is expected to reach 1.7 million British
