采用抗病品种仅能部分地防治由Verticillium dahliae病原菌引起的棉花黄萎病,因为抗病力高的品种很少见,所以人们寻求其它的防治方法。内吸杀菌剂如苯菌灵也只能局部有效且不经济。化学防治黄萎病的研究结果表明:生长延缓剂推迟黄萎病的发生并略微减轻病情指数以及减少叶柄内黄萎病菌繁殖体的数目。本文广泛地研究这些无杀菌毒性而有生物活性的化合物的田间试验结果,在田间测定化合物抑制植物体内黄萎病菌的数目和籽棉产量的影响。
The use of resistant varieties can only partially prevent and control Verticillium dahliae caused by Verticillium dahliae pathogen, because the high resistance varieties are rare, so people are looking for other control methods. Inhaler fungicides such as benomyl are also only locally effective and not economical. The results of chemical prevention and treatment of Verticillium wilt showed that the growth retardants delayed the occurrence of Verticillium wilt, slightly reduced the disease index and reduced the number of Verticillium dahliae propagules in the petiole. In this paper, the field trials of these non-germicidal and bioactive compounds were extensively studied to determine the effect of compounds on the inhibition of Verticillium dahliae in plants and seed cotton yields in the field.
