随着麦棉两熟制的推行,棉田三代棉铃虫已成为我市夏播棉上的主要害虫。防治此代正逢盛夏季节,常规喷药非但工效低且易发生中毒事故,寻找一种快速有效而又安全的施药方法,乃是生产上急待解决的问题。1983年我们参考有关资料,在市植保站的协助下,进行棉田低量喷药试验。两次共试防120亩次,经过四次多点反复调查证明,低容量施药防治棉田三代棉铃虫有快速、高效、安全和省工的优点。现将有关此项工作的情况提出,供参考。
With the implementation of double cropping of wheat and cotton, the third generation of cotton bollworm has become the main pest on summer cotton in our city. Prevention and treatment of this generation is coinciding with the summer season, conventional spraying not only inefficient and prone to poisoning accidents, looking for a fast and effective and safe method of application, but the production is an urgent problem to be solved. In 1983 we refer to the relevant information, with the assistance of the plant protection stations, low-dose cotton field spraying test. Twice a total of 120 mu defense, after repeated investigations more than four times to prove that low-capacity cotton seedling control three generations of cotton bollworm has the advantages of fast, efficient, safe and labor-saving. The work of this situation is now for reference.
