笔花豆炭疽病大田防治试验研究

CHEMICAL CONTROL OF ANTHRACNOSE ON STYLOSANTHESSPP. IN THE FIELD

格拉姆笔花豆炭疽病在海南危害严重。大田化学防治试验表明,应用20％多菌灵乳剂,有效成分450g/hm^2·次,在作物生长期和花期,连续喷药3次,可获得满意的防治效果,产量增加36％～60.8％。

Hainan records severe anthracnose incidence on Stylosanthes guianensis cv. Graham. Field experiments of chemical control shows that a successive spray (thrice) of 25% carbendazim (emulsion) to the crop at 450 g a. i. /h during the growing and flowering periods achieved satisfactory effects in the disease control and gave a yield increase ranging from 28% to 61.5%.
