雅安地区常年稻瘟病发病面积在10万亩左右,占稻田面积的20％,损失产量1千万斤以上。由于水稻品种对稻瘟病的抗性丧失较快,在推广抗病品种的同时,还必须作好药剂防治,才能控制其危害,为了找出比现在生产上使用的“异稻瘟净”更为有效的药剂,1981年我们在雅安县草坝公社作了稻瘟灵(富士一号)的药剂防治试验和示范。
The annual area of rice blast in Ya’an is about 10 mu, accounting for 20% of the total area of the paddy field and losing more than 10 million kg of output.
