50％硫悬浮剂是中国农科院植保所的科研成果。于1986年11月已通过化工部鉴定,并投入生产。这种制剂以硫磺为主要原料,并辅以其他助剂。由于配方合理,工艺先进,粒径均小于2微米,悬浮率高(大于90％),喷雾后粘着力强,耐雨水冲刷,能充分发挥药效。外观为白色或灰白色粘稠状液体,放置过久,在上层有水液析出,摇动后又很快恢复悬浮状态。在51℃+1℃热贮4周,在-10℃～-15℃冷贮24小时,不变质,不结冻,仍具有流动性,悬浮率在原悬浮率的90％以上,能与任意比例的水混合。对小麦白粉病菌分生孢子的萌发有抑制作用,能杀死叶螨及螨卵。因此,可有效地防治小麦白粉病、黄瓜白粉病、哈密
50% sulfur SCF is the Chinese Academy of Agricultural Sciences research results. In November 1986 passed the Ministry of Chemical Industry identified and put into production. The preparation of sulfur as the main raw material, supplemented by other additives. As the formula is reasonable, advanced technology, particle size is less than 2 microns, high suspension rate (greater than 90%), spray strong adhesion, resistance to rain erosion, can give full play to efficacy. The appearance of white or gray viscous liquid, placed too long, there is water in the upper layer precipitation, and quickly returned to suspension after shaking. Heat stored at 51 ℃ + 1 ℃ for 4 weeks, stored at -10 ℃ ~ -15 ℃ for 24 hours, not degenerate, not frozen, still have fluidity, the suspension rate of more than 90% of the original suspension rate, with any ratio Water mix. On wheat powdery mildew conidia germination inhibition, can kill spider mites and mite eggs. Therefore, it can effectively control wheat powdery mildew, cucumber powdery mildew, Hami
