可溶性硅源制剂对葡萄霜霉病的抑菌防病效果研究

The Inhibition Effect of Preparation of Soluble Silica Sources on Grape Downy Mildew

以不同的可溶性硅源制剂和药物对照制剂研究表明,各种硅源制剂对葡萄霜霉菌均有明显的抑制作用,但不同浓度SiO2水溶胶对葡萄霜霉病的防治效果明显好于硅酸钠、正硅酸乙酯,而且以2.0g/L的SiO2水溶胶的防治效果最好,并接近于800倍的50%多菌灵可湿性粉剂的防治效果。

The effect of different dreparation of soluble silica source and drug control agents on grape downy mildew was studied. The grape downy mildew was significantly inhibited by preparation of various silica sources. Different concentrations of SiO2 Hydrosol preventive effect of grape downy mildew significantly better than sodium silicate, TEOS,SiO2 Hydrosol with 2.0g / L of the best control effect, and close to 800 times the 50% Carbendazim WP control effect.
