新型高效杀菌剂氟吗啉

氟吗啉是以邻苯二酚为原料制得的新型内吸性杀菌剂。试验表明,氟吗啉在100～200mg/L(相当于100～200g a.i./hm2)剂量下对卵菌纲病原菌引起的黄瓜霜霉病、白菜霜霉病、番茄晚疫病、辣椒疫病、葡萄霜霉病等具有优异的活性。毒理(性)结果表明其对哺乳动物低毒。氟吗啉对酰胺类杀菌剂(如甲霜灵)的抗性或敏感菌株均有活性,具有优异的保护活性、治疗活性和抑制孢子萌发活性,持效期长,无药害,对作物安全,增产效果明显(通常增产20％～50％)。

New High Efficiency Fungicide, Flumorph

Fumorph is a new systemic fungicide, which is made from o-dihydroxybenzene. Tests indicated that flu-morph has perfect activity against the diseases caused by oomycetes such as downy mildew of cucumber, downy mildew of Chinese cabbage, late blight of tomato, late blight of potato, downy mildew of grape at the dosage of 100 - 200g a. i. /hm2. The toxicity test has showed that flumorph has low toxicity to mammalian. Flumorph has activity against the resistance or sensitive strain of acid amide fungicides (such as metalaxyl) , and characterized by perfect protection activity, therapeutical activity and inhibition activity against spore germination, long effect, safe and notable action on increase of crop production ( usual increment is 20% - 50% ).
