川东涪陵地区小麦病害以白粉病、赤霉病为主,流行年发生面积近百万亩,占全区播种面积的一半,损失约3千万斤。尤以白粉病发生普遍,多年来用“石硫合剂”防治起了一定作用,但由于熬制费工以及发病期气候条件恶劣影响施药质量,田间药效常不够理想,且生长后期赤霉病、条锈病并发,“石硫合剂”基本无效,又需更换药剂品种,增加施药次数,加大投资。群众迫切要求高效、经济、兼治的防治技术。近年,参加省植保所协作对我区常发的两病进行了粉锈宁、托布津单用、混用及施药方法研究。
Fuling wheat in eastern Sichuan Province with powdery mildew disease, scab, the prevalence area of nearly one million mu, accounting for half of the sown area, loss of about 30 million kg. In particular, the occurrence of powdery mildew is common and it has played a certain role in the prevention and treatment of “limestone” for many years. However, due to poor working conditions and poor weather conditions, the field efficacy is often not ideal enough, Disease and stripe rust concurrency, “lime sulfur mixture” basically ineffective, but also need to replace the drug varieties, increase the frequency of application, increase investment. The people urgently demand efficient, economical and effective prevention and control technologies. In recent years, to participate in the cooperation of the Provincial Plant Protection Institute of our frequent cases of the two diseases were triadimefon, Topaz alone, mixing and application methods.
