Application example
Experiment of field drug effect
Reagent to be tested: agents prepared in examples 1 to 3 and comparative examples 1 to 3
Weed control subjects: crab grass and green bristlegrass herb
The test method comprises the following steps: selecting 4 grasslands with 8 square meters and uniform grass phase for each treatment, randomly arranging the grasslands, carrying out spraying treatment according to the glyphosate effective component 60 g/mu and the water consumption of 30L/mu, respectively carrying out pesticide effect observation after 7 days of treatment, and recording fresh weight control effect after 14 days; water was used as a blank.
The fresh weight control effect calculation method comprises the following steps: fresh weight control effect (fresh weight of weeds in blank control zone-fresh weight of weeds in treated zone)/fresh weight of weeds in blank control zone 100%
Table 1 shows the results of the observation test 7 days after the application; table 2 fresh weight control effect measured 14 days after application.
TABLE 1
As shown in the test results in Table 1, the aqueous glyphosate solutions prepared in examples 1 to 3 showed signs of wilting, lodging, blackening of heart and leaves, and slight yellowing of roots after 7 days treatment of weeds; after the glyphosate aqueous solution prepared by the comparative example is used for treating weeds for 7 days, only the symptoms of wilting, lodging and slight poisoning appear, and the symptoms of abnormal heart leaves and roots do not appear; the components of the glyphosate aqueous solution produce a certain synergistic effect, so that the glyphosate aqueous solution has more obvious effect and better quick action; and the experimental effect of the example 3 and the comparative example 3 shows that the glyphosate water agent containing the pinellia ternate water extract has better quick-acting performance compared with the chinaberry water extract.
TABLE 2
The data in table 2 show that the weeding effect of the glyphosate aqueous solution is significantly higher than that of the glyphosate aqueous solution prepared in a comparative example, and the experimental data of the example 3 and the comparative example 3 show that the pinellia ternate aqueous extract has a more significant synergistic effect on glyphosate than the melia azedarach aqueous extract.
In conclusion, the plant-source synergistic component pinellia ternate is added, so that the conduction of glyphosate in the bodies of weeds can be effectively promoted, particularly the conduction to roots is promoted, the quick action and the final control effect are improved, and the glyphosate aqueous solution has a remarkable weeding effect and is beneficial to market popularization and application.
