In order to further illustrate the present invention, the following detailed description of the invention is given in conjunction with examples, which should not be construed as limiting the scope of the invention.
Example 1
25% chloroquine isopropyl phosphate wettable powder: 12.5g of dichloroquine isopropyl phosphate, 0.7 g of sodium dodecyl sulfate, 0.7 g of magnesium aluminum silicate, 1.5 g of dodecyl sodium sulfonate, 2.0 g of silicon dioxide, 32.1 g of talcum powder, 0.5 g of hexadecanol and 50 g of total amount are adopted, pre-crushed and then crushed by a superfine powder jet mill to prepare the superfine powder wettable powder, the suspension percentage is 78 percent, and the wetting time is 2.7 minutes.
Example 2
25% chloroquine isopropyl phosphate wettable powder: 12.5g of dichloroquine isopropyl phosphate, 0.75 g of sodium dodecyl sulfate, 0.75 g of magnesium aluminum silicate, 2.0 g of dodecyl sodium sulfonate, 2.5g of silicon dioxide, 31 g of talcum powder, 0.5 g of hexadecanol and 50 g of total amount are adopted, pre-crushed and then crushed by an ultrafine airflow crusher to prepare the ultrafine powder wettable powder, the suspension percentage is 90%, and the wetting time is 2.1 minutes.
Example 3
After the rice is transplanted, the herbicide is applied to weeds in the 2-4 leaf stage, the stems and leaves are sprayed with 1 time of the 25% quinclorac isopropyl wettable powder prepared in the example 1, and the using amount of the active ingredients of the quinclorac isopropyl is 112.5g of a.i./hm 2 The number of plants was measured at 15 days after application, and the number of plants and fresh weight were measured at 30 days after application, with the results shown in tables 1 to 3. Wherein the barnyard grass in the double-Yashan welfare area belongs to a sensitive type, the barnyard grass in the Fujin area belongs to a medium resistant type, and the barnyard grass in the Tonghe area belongs to a high resistant type.
The prevention effect calculation method comprises the following steps:
TABLE 1 control of plant number 15 days after application
| Treatment of | Double duck mountain welfare (sensitivity S1) | Fujin (anti-R1) | Tonghe (Gao kang R2) |
| Quinclorac acid isopropyl ester | 86.9％ | 78.2％ | 75.4％ |
TABLE 2 control of plant number 30 days after application
TABLE 3 fresh weight control effect 30 days after application
As can be seen from tables 1-3, the single dosage of the 25 percent quinclorac isopropyl chloride wettable powder has the control effect on sensitive barnyard grass (in the double-duck mountain welfare area) of 86.9 to 89.1 percent, the fresh weight control effect of 92.6 percent, the control effect on high-resistance barnyard grass (in the river-crossing area) of 75.4 to 78.4 percent and the fresh weight control effect of 79.9 percent.
Comparative example 1
After the rice is transplanted, in the 2-4 leaf stage of barnyard grass, 1 time of 25% quinclorac wettable powder single agent is sprayed on the stem leaves, and the dosage of the effective component is 112.5g a.i./hm 2 The number of plants controlling effect was measured 15 days after the application of the drug, and the number of plants controlling effect and fresh weight controlling effect were measured 30 days after the application of the drug, and the results are shown in tables 4 to 6.
TABLE 4 control of plant number 15 days after application
| Treatment of | Double duck mountain welfare (sensitivity S1) | Fujin (anti-R1) | Tonghe (Gao kang R2) |
