1987年,我县1万余亩花生地使用地乐胺防除杂草,收到了显著效益。通过多点试验和大面积示范,总结如下: 1.防草效果好 旱地花生亩用48％地乐胺乳油(下同)150—200毫升除草效果93.5—97.3％;水田花生200毫升平均防效92.3％;地膜覆盖花生防效达96％。对马唐、狗尾草和稗草等有特效,对多年生莎草科杂草防效差。 2.省工节支 往年花生中耕锄草两遍,每亩花工8—10个,草害严重的花工更多。用地乐胺除草,每亩只需花施药工0.2个,培土工1个;每工以3元计节支20.4—26.4元。并较好地解决了花生锄草用工与早稻田
In 1987, more than ten thousand mu of peanut in our county used detemore to control weeds and received significant benefits. Through multi-point experiments and a large area demonstration, summarized as follows: 1. Anti-grass effect of dry land peanut acres with 48% toxetil EC (the same below) 150-200 ml weeding 93.5-97.3%; paddy peanut 200 ml average anti-efficacy 92.3%; peanut mulching effect 96%. Crabgrass, Setaria and barnyardgrass have special effects, perennial sedge weeds poor control effect. 2. Provincial Labor Support Perennial cultivating weeds in the past two times, 8-10 acres per acre, grass serious damage more. Landlot herbicides, only 0.2 yuan per acre spent pesticide, earthwork workers a; 3 dollars per work plan 20.4-26.4 yuan. And a better solution to the peanut weeding and Waseda
