热带作物园地上发生的草害,对生产影响很大.人工除草,花工大、收效低.为了探讨药效快速、持久、良好、毒性小、无药害的除草剂,我们进行了一些试验.现将试验的初步结果整理如下:试验材料和方法供试除草剂有克无踪(Gramoxone又名百草枯,我省一九七九年从日本进货,其剂型为20%乳剂)、镇草宁(Glyphosate又名草甘磷,国内镇江农药厂生产的10%乳剂)、2,4—滴(沈阳化工厂生产,含2,4—滴纳盐80%粉剂).一、茅草[Imperata Cylindrical(L.)Beauv.]的药效反应:
Tropical crop garden ground grass damage, a great impact on the production of artificial weeding, large flower, low efficiency.In order to explore the efficacy of fast, long-lasting, good, less toxic, non-harmful herbicides, we conducted some experiments. The preliminary results of the test are summarized as follows: Test materials and methods The test herbicide has no trace (Gramoxone also known as paraquat, our province in 1979 from Japan, the dosage form of 20% emulsion), the town of grass rather (Glyphosate, also known as glyphosate, the domestic Zhenjiang Pesticide Factory 10% emulsion), 2,4-drop (Shenyang Chemical Plant production, containing 2,4- sodium salt 80% powder.)
