Embodiment 4
To pesticide obtained in embodiment 1, embodiment 2, embodiment 3, comparative example 1, comparative example 2, comparative example 3, comparative example 4
The suspensibility of suspending agent is measured with the pesticide adhesive rate after pestsides synthesis, and every group carries out parallel test.
Measuring method:
Suspensibility: it is measured using " GB/T14825-2006 agricultural-chemical suspension rate measuring method "；
Pesticide adhesive rate: being diluted with water 1000 times for pesticide, adds agricultural chemicals suspension agent by the 5% of pesticide quality, then uses
1mL solution is evenly coated on vertical coverslip by pipettor, and the pesticide volume on coverslip is measured after standing 5min；The agriculture of use
Medicine is insecticide (chlopyrifos), when pesticide individually measures, is measured after pesticide is diluted with water 1000 times.
Measurement result:
Table 1 is ridge soil powder and sodium pyrosulfite, sodium acrylate suspensibility and pesticide adhesive rate under the conditions of different quality ratio
Measurement result
As it can be seen from table 1 its suspensibility of agricultural chemicals suspension agent obtained is 54% when kaolin is without radiation treatment,
Pesticide adhesive rate is 47%, and suspensibility and pesticide adhesive rate are below radiation treatment group；When kaolin powder and sodium pyrosulfite,
When the mass ratio of sodium acrylate is 30:1:2, three is matched not in the ratio range of embodiment group, and suspensibility is significantly lower than
Embodiment group；The measurement result of pesticide adhesive rate is greater than pesticide (chlopyrifos) independent measurement result in embodiment 1- embodiment 3.

Embodiment group, when the mass concentration of aqueous suspension ofkaolin continues to increase to 60g/L, suspensibility is not continued growing, instead
Declined.
Table 3 is comparative example 5,1 suspensibility of embodiment and pesticide adhesive rate measurement result
From table 3 it can be seen that being lost and degrading using a kind of new and effective control pesticide of patent CN201310042997.2
Method in pesticide pesticide control obtained lose agent, suspensibility and pesticide adhesive rate measurement result are below the measurement of embodiment group
As a result.
