The stability test result for the chlopyrifos water dispersible granules that 1 embodiment of the present invention 1~8 of table and comparative example 1~3 obtain
Known by table 1, the product stability in the embodiment of the present invention is preferable, and the disintegration and the variation of aqueous suspension rate after heat storage are not
Greatly, after specific preferred auxiliary agent has especially been selected in Examples 1 to 4, property indices are better, and aqueous suspension rate exists
94% or more, reach as high as 97.4%.
Rice terrace planthopper prevents field control effectiveness test
Test medicine：
Chlopyrifos water dispersible granules made from the embodiment of the present invention 1~8 and comparative example 1~3；
Comparison medicament is：480g/L chlopyrifos EC (is purchased from Shandong Dongtai Agrochemical Co., Ltd).
Experimental condition and application method：
This experiment is arranged in the progress of the Feixi County towns San He, and prevention planthopper carries out in late rice, and preceding stubble is early rice.
Experimental field fertility uniformity, topography are flat.The inclined sand mold of soil, middle fertility.Rice is in milk stage when experiment, in planthopper
Deng generation.Medical instruments use -16 type knapsack sprayer of workers and peasants, spouting liquid 50kg/667m2, artificial even spraying.Field when dispenser
Between keep 3~5cm of water layer, 7d is retained after medicine, so that drug effect plays.Investigate insect population before dispenser, 7,14d is adjusted respectively after medicine
Residual borer population living is looked into, Revision insect recluced rate and Rectifying efficacies are calculated.Its control effect see the table below 2, and table 2 is the embodiment of the present invention 1~8
With the chlopyrifos water dispersible granules in comparative example 1~2 to the preventive effect of rice terrace planthopper.
The check plot is clear water check plot, does not spray medicament.
Chlopyrifos water dispersible granules in 2 embodiment of the present invention 1~8 of table and comparative example 1~3 prevent rice terrace planthopper
Effect
As can be seen from Table 2, the present invention in chlopyrifos water dispersible granules preventive effect be maintained at 85% or more, by match with
And the optimizely select of different type auxiliary agent is matched, the water dispersible granules drug effect as obtained by Examples 1 to 44 is more preferably.Without containing chela of the present invention
The water dispersible granules and comparative example 3 of the comparative example 1~2 of mixture use the water dispersible granules of other kind of quasi-chelate compound since it is anti-
Hard water effect is poor, therefore preventive effect is relatively poor.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
