摘要
为明确植物源除草剂Pure对杂草的防除效果和使用技术,在非耕地上进行杂草防除试验。结果表明,植物源除草剂Pure以112.5、150 kg/hm^2株防效最好,施药后3~28 d的株防效为79.26%~94.25%;植物源除草剂Pure以150 kg/hm^2对鲜质量防效最好,施药后3~28 d的鲜质量防效为88.15%~93.47%,均与对照药剂20%百草枯水剂用量3 kg/hm^2的鲜质量防效无显著性差异。因此植物源除草剂Pure防除非耕地杂草的适宜用量为150 kg/hm^2。
An experiment was conducted in an uncultivated field to determine the efficacy of the botanical herbicide Pure.The most effective doses of the botanical herbicide were 112. 5 and 150 kg / hm^2 that provided 79. 3% to 94. 2% at 3 ~ 28 days after application. The greatest fresh reduction（ 88. 2 ~ 93. 5%） was obtained at 3 ~ 28 days after application when the botanical herbicide was sprayed at 150 kg / hm^2,that was similar to that obtained with the reference commercial herbicide- paraquat 20% AS at 3 kg / hm^2. Thereofore the appropriate dose of botanical herbicide Pure to control weeds was150 kg / hm^2 in the uncultivated field.
