美国贝兹维尔农业研究中心已研制成功一种新的除草剂,编号为6706,这是一种与现有除草剂吡拉松相近的物质,目前正试用以消灭大田和园艺作物的阔叶草和杂草。此剂与吡拉松不同,吡拉松是抑制杂草生长,使杂草干枯和绿叶死亡,此剂主要是使叶色变白,能直接阻止光合作用。在阻止光合作用方面,吡拉松和6706虽有同效,但6706的有效期较长。 A new herbicide, code number 6706, has been developed by the Center for Agricultural Research in the States of Batesville, US, which is a substance similar to the existing herbicide Pirathon and is currently being tested on broad-leaved grass used to destroy fields and horticultural crops And weeds. This agent is different from Piraeus, Piraeus is weed growth inhibition, dry weeds and green leaf death, this agent is mainly to make the leaf color white, can directly prevent photosynthesis. In terms of preventing photosynthesis, although Prazosin and 6706 have the same effect, 6706 has a longer effective period.
