0.3 gram of ether phosphate, 0.2 gram of NPE, 0.5 gram of propane diols supplies deionized water to 10 milliliters, using at a high speed
Homogenizer is uniform, and 30% aqueous emulsion is made.
Embodiment 4
Bakanae disease of rice is prevented and treated with composition pesticide seed soaking made from above-described embodiment 2 and 3.Test process：This experiment with
25% Prochloraz missible oil is as comparison medicament, and comparison medicament is soaked seed according to label concentration.It is Huaihe River rice No. 11 for examination rice varieties.Leaching
Vernalization is to the sowing that shows money or valuables one carries unintentionally after kind of 25 DEG C of temperature, seed soaking time 48 hours, seed soaking enough time.Seedling raising method is dry rice seedling, the length of time rice seedlings grow
Crop field is transplanted after 20 days.Tillering stage and Filling stage investigation bakanae disease strain rate simultaneously calculate preventive effect.
For examination rice varieties Huaihe River rice, No. 11 carry anti-Prochloraz fusarium moniliforme.Result of the test shows that the present invention is implemented
Example 2, embodiment 3 dilute 500 times of seed soakings has excellent preventive effect to paddy rice seed-borne disease bakanae disease, its tillering stage and booting
Phase illustrates the seed treatment composition manufactured using inventive formulation to rice bakanae disease the effect of bakanae disease up to more than 90%
Disease has excellent prevention effect.Due to there is the resistance to the action of a drug, this experimental control medicine to Prochloraz for examination rice varieties Fusarium moniliforme Sheld
Agent Prochloraz is poor to bakanae disease preventive effect, and tillering stage and boot stage preventive effect are below 60%, such as table 2.
The preventive effect kind of medicament manufactured by the embodiment of the present invention of table 2 to bakanae disease of rice：Huaihe River rice 11
