我们于1985年——1987年在江西省内调查,发现多种柄锈菌(Puccinia)均可引起禾本科牧草锈病。禾草感病后光合效率下降,呼吸强度及蒸腾强度显著提高,导致牧草产量下降及品质变劣。据国外报道,有些锈菌还可使家畜中毒。1987年,我们用粉锈宁、敌锈钠、石硫合剂对黑麦草锈病进行了田间药效试验,现将试验结果整理如下。 We surveyed in Jiangxi Province from 1985 to 1987 and found that many Puccinia species can cause grass pasture rust. Grass photosynthetic decline after the flu, respiratory intensity and transpiration increased significantly, resulting in decreased yield and quality fodder grass. According to foreign reports, some rust can also make livestock poisoning. In 1987, we used triadimefon, enemy rust sodium, lime sulfur rust rye grass rust field efficacy test, the test results are summarized below.
