FIG. 1 shows the results of comparing the stabilities of 5 pesticides a to e selected in example 8 and comparative example 1, respectively, and FIG. 2 shows the results of comparing the stabilities of 3 pesticides a to C selected in example 8 and comparative example 1, respectively, wherein the left side of each group of the pesticides in the figure is the pesticide corresponding to comparative example 1, and the right side is the pesticide corresponding to example 8.
By comparison, the agents of comparative example 1 were found to exhibit more or less delamination, while the agent of example 8 was found to be more consistent, indicating that the agent of example 8 has better stability.
Test example 1
The pesticide systems formed after the pesticides of examples 8-14 were selected as different pesticides were observed for flocculation, delamination, and the time for which the systems remained stable. Wherein, a pesticide system formed by respectively compounding potassium dihydrogen phosphate aqueous solution (40g/L) and pesticides of different formulations is used as a control group.
As shown in table 1, the control groups formed by compounding the potassium dihydrogen phosphate aqueous solution with representative formulations of the suspending agent, the aqueous emulsion, the emulsifiable concentrate, the microemulsion, the dry suspending agent and the like all showed flocculation, delamination and the like, but most of the pesticide systems formed by compounding the potassium dihydrogen phosphate aqueous solution, the flight control adjuvant and the pesticide all showed good stability except for occasional occurrence of a few precipitates, which indicates that the stability of the pesticide systems can be effectively improved by adding a proper amount of the flight control adjuvant into the compounding system of the potassium dihydrogen phosphate aqueous solution and the pesticide.
TABLE 1
Test example 2
The pesticide systems formed after the pesticides of examples 8-14 were selected for different pesticide packages were observed for flocculation, delamination, and the time for which the systems remained stable. Wherein, a pesticide system formed by respectively compounding potassium dihydrogen phosphate aqueous solution (40g/L) and pesticides of different formulations is used as a control group.
The observation results are shown in table 2, the control group formed by compounding the potassium dihydrogen phosphate aqueous solution with 3 different pesticide packages respectively has the phenomena of flocculation, delamination and the like, but most of the pesticide system formed by compounding the potassium dihydrogen phosphate aqueous solution, the flying prevention aid and the pesticide has good stability except that a little precipitate occasionally appears, which shows that the stability of the pesticide system can be effectively improved by adding a proper amount of the flying prevention aid into the compound system of the potassium dihydrogen phosphate aqueous solution and the pesticide packages.
TABLE 2
Test example 3
The pesticides of examples 8 to 14 were selected as a wheat pesticide package, and the corresponding agents were sprayed on wheat crops with an unmanned aerial vehicle at a dose of 1.0L/mu, and then the control effects of each group of agents on aphids, sheath blight and gibberellic disease, and the growth of ears were observed and counted. Wherein, potassium dihydrogen phosphate aqueous solution (40g/L) is respectively compounded with wheat pesticide packages to form a medicament as a control group.
Wherein, the wheat pesticide package is as follows: 20g of 30% thiamethoxam high-chlorine fluoride and 20g of 32% thifluzamide tebuconazole suspending agent, 20g of 40% prochloraz tebuconazole aqueous emulsion and 40 g.
The statistical results are shown in table 3, in the control group formed by compounding the potassium dihydrogen phosphate aqueous solution and the wheat pesticide package, the control effect on wheat aphids is only 50.2%, the control effect on banded sclerotial blight is only 63.2%, and the control effect on gibberellic disease is only 48.7%. In the corresponding medicament formed in the embodiment 8-14, the control effect of wheat aphid is 88.3-99.1%, the control effect of sheath blight is 86.7-93.2%, and the control effect of gibberellic disease is 88.7-94.3%, which is obviously superior to the control effect of a control group. Meanwhile, compared with a control group, the difference between the grain number per ear and the thousand grain weight of the medicaments correspondingly formed in the examples 8 to 14 is obvious, and the medicament provided by the embodiment of the invention has good growth promoting and yield increasing effects.
