我站在去年棉田化学除草试验的基础上,一九七三年继续进行棉田化学除草剂试验,进一步摸索适于棉田除草效果高,对棉株无药害,药原较多,成本低的除草剂品种,并在施用量及施用方法和时期上进行试验,现将果结整理如下。供试药剂为: 10％除草醚可湿性粉剂上海农药厂 50％扑草净可湿性粉剂昆明农药厂 25％敌草隆可湿性粉剂无锡惠山农药厂 50％利谷隆可湿性粉剂日本进口 50％莠谷隆可湿性粉剂瑞士进口 8.5％稻草完-S颗粒日本进口 (一) 除草醚,扑草净、敌草隆三种除草剂,不同时期,不同方法的药效比较。
On the basis of last year’s chemical herbicide test in cotton fields, I continued to carry out chemical herbicide tests in cotton fields in 1973 and further explored suitable herbicides suitable for weeding in cotton fields with high levels of herbicide-free, herbicides and low cost Agent varieties, and in the application rate and application method and time on the test, the results are as follows. Test agents are as follows: 10% of weeding ether WP Shanghai pesticide factory 50% prometryne WP WP Kunming Pesticide Factory 25% Diuron wettable powder Wuxi Huishan Pesticide Factory 50% Liurong WP 50 Japan imported 50 % Transglutaminase WP Switzerland imported 8.5% straw-S granules Japan imported (a) weeding ether, prometryne and diuron three herbicides, different periods, different methods of efficacy comparison.
