1972年,我们对近年来国产的一些主要防锈药剂,进行了田间防治试验,证明萎锈灵防治效果较为理想。萎锈灵(D735)是一种新的低毒选择性内吸杀菌剂。有效成分为2,3——二氢——5甲酰替苯胺——6——甲基——1,4——氧硫杂芑。它能阻止许多担子菌的菌丝生长。去年田间试验的药剂样品由天津农药厂供给,小麦品种为易染病品种“5389”,经自然感染发病后(条、叶锈混生),于5月17日和23日各喷药一次,每亩喷液约250斤。5月31日调查,防治效果显著,200倍和
In 1972, we carried out field control trials on some of the major anti-rust agents made in China in recent years, and proved that the control effect of carbendazim is ideal. Carbendazim (D735) is a new low toxic selective systemic fungicide. The active ingredient is 2,3-dihydro-5-formyl anilide-6-methyl-1,4-oxathiazepine. It stops the mycelium growth of many basidiomycetes. The pesticide samples from the field trials last year were supplied by Tianjin Pesticide Factory. The wheat varieties were susceptible to the disease “5389”. After the onset of natural infection (stripe rust and leaf rust mixed), spraying was conducted once on May 17 and 23, Spray about 250 pounds. May 31 investigation, prevention and treatment of significant effect, 200 times and
