Second component is the adhesivity injecting, water intaking glue 20-40 part (weight portion, each part is equal in weight with component 1), polyethylene glycol 2-3 part, maltose 30-40 part is after elder generation is heated to boil-off separating with weight water such as glue add, again with maltose, heated and stirred is to molten entirely, and it is even to put a small amount of water-reducible polyethylene glycol into agitator;

With Chinese herbal medicine leachate 90% and adhesivity injecting 10%, put in the reactor, add water 50%, mixed at normal temperatures 1 hour, i.e. cost product stoste.

This product stoste is used efficacy stability down at 40 ℃, can deposit under the normal temperature 3 years, there is sediment also not influence drug effect after depositing, thin up 600-1500 doubly mixes during use, even spraying is used, the fungi that all kinds of crops, vegetables, melon and fruit are contaminated has killing effect, is mainly used in and kills gray mold, downy mildew, anthracnose, early blight, late blight, leaf spot, spot blight, blight, fruit tree putrefaction disease, spot stripe, rice blast, cure rate all more than 90%.
