除草剂的生物评价包括除草效果和作物安全(选择)性估价等试验内容,在满足准则中各项条件下,根据杂草的发生情况,这些试验可对杂草防治能力或作物安全性做出评价,本文对单一试验的处理作了详细介绍,同时也对总体评价项目包括其它试验(应用试验、后作物试验,品种试验等——附录1)作了概述,粮农组织(FAO)效价准则就这一类试验提供了一般背景资料。一、试验条件 1.作物和栽培品种本准则涉及陆稻(旱播)、或水稻湿播,或移植水稻除草剂的效果
Biological evaluation of herbicides includes tests on herbicidal efficacy and crop safety (selection) evaluation, which meet the criteria of the criteria for weed control, or crop safety, based on the occurrence of weeds In this paper, the treatment of a single test is described in detail, and an overview of the overall evaluation project including other tests (applied test, post-crop test, variety test - Appendix 1), FAO’s titers This type of experiment provides general background information.
