在农业现代化的时代,由于高产品种、肥料、农场机械化操作等技术的采用,大多数作物的单位面积产量都相继达到了较高的水平,很有必要将各种病虫害控制在检测极限之下以稳定产量。根据印度农药协会的一篇报告,全世界由真菌病原引起的植物病害大约有10000种,在印度造成的损失约占作物年度总损失的26%。农药工业研究小组断定,由虫害和病害造成的粮谷损失有800～1000万吨。除此之外,尚有真菌毒素引起的对动物和人类的间接危害。若采用适当的防治措施,能避免70～80%的损失。所以,作物保护措施对粮食安全生产来说是必不可少的。
In the era of agricultural modernization, due to the adoption of technologies such as high-yielding varieties, fertilizers and farm mechanized operations, the yield per unit area of most crops has successively reached a high level. It is therefore necessary to control various pests and diseases under the limit of detection Stable production. According to a report by the Indian Pesticide Association, there are about 10,000 plant diseases caused by fungal pathogens in the world, accounting for about 26% of total annual crop losses in India. Pesticide industry research team concluded that the grain losses caused by pests and diseases have 800 to 10 million tons. In addition, there are mycotoxins cause indirect harm to animals and humans. If using appropriate control measures, to avoid 70 to 80% of the losses. Therefore, crop protection measures are essential for the production of food security.
