In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is an insecticidal composition, which comprises the following components: 2.5% of emamectin benzoate, 5% of dicyclopropyl tetramethrin, 10% of cyclohexanone, 16% of an emulsifier, 1% of an antioxidant and the balance of water;
the preparation method of the insecticidal composition comprises the following steps:
Step 1: dissolving emamectin benzoate and dicyclopropyl tetramethrin by using cyclohexanone;
Step 2: adding an antioxidant into the product obtained in the step 1, and mixing and stirring the mixture until the mixture is uniform and transparent;
And step 3: and (3) adding an emulsifier into the product obtained in the step (2), adding water, mixing and stirring uniformly to prepare the microemulsion insecticidal composition consisting of 7.5% of emamectin benzoate and dicyclopropyl grease.
When in use, the microemulsion of the emamectin benzoate and the dicyclopropyl cinfenot of 7.5 percent is diluted by adding water of 2500 times and sprayed for use, which has special effect on preventing and treating aphids, and the preventing and treating effects of the microemulsion of the emamectin benzoate and the dicyclopropyl cinfenot are respectively 88.4 percent, 97.6 percent and 94.9 percent after 1 day, 7 days and 15 days after the application. After 5% of single preparation of emamectin benzoate and dicyclopropyl tetramethrin is used by spraying after being diluted 2500, the control effect 1 day after the pesticide is respectively 78.3% and 62.4%; the control effect 7 days after the pesticide is 68.9 percent and 85.5 percent respectively; the control effect 15 days after the pesticide is 61.9 percent and 80.5 percent respectively. It can be seen that the prevention and treatment effect is greatly improved after the emamectin benzoate and the dicyclopropanate are compounded, and the quick action and the persistence are better than those of single dosage.
Example two: an insecticidal composition comprises the following components: 3% of emamectin benzoate, 30% of dicyclopropyl tetramat, 6% of phosphate, 0.16% of xanthan gum, 0.4% of preservative, 1% of antioxidant and the balance of water;
The preparation method of the insecticidal composition comprises the following steps:
Step 1: pouring water into a stirring kettle, then sequentially adding phosphate ester, emamectin benzoate, dicyclopropyl tetramat, xanthan gum, preservative and antioxidant, shearing and stirring for 30 minutes;
Step 2: and (3) performing serial sanding on the product obtained in the step (1) by using 3 sanding machines to prepare the suspending agent-state insecticidal composition consisting of 33 percent of emamectin benzoate and bialaphos.
When in use, the emamectin benzoate and the dicyclopropyl tetramethrin in 33 percent are diluted by 5000 times of water and sprayed for use, and the control effect on the thrips is special, and the control effect on 1 day, 7 days and 15 days after the application is respectively 90.4 percent, 98.6 percent and 96.3 percent. The single dose of 5 percent of emamectin benzoate and dicyclopropangolin is diluted by 2500 times, and after the single dose is used under the same condition, the control effect 1 day after the single dose is 75.3 percent and 52.4 percent respectively; the control effect 7 days after the pesticide is 57.9 percent and 87.3 percent respectively; the control effect 15 days after the pesticide is 47.5 percent and 83.7 percent respectively. It can be seen that the synergistic effect of the emamectin benzoate and the dicyclopropanate after compounding is very obvious, the control effect on the thrips is greatly improved, and the quick-acting property and the lasting property are both superior to those of a single agent.
in a third embodiment, an insecticidal composition comprises the following components: 2% of emamectin benzoate, 10% of dicyclopropanate, 18% of emulsifier, 2% of organic soil, 1% of antioxidant and the balance of methyl esterified vegetable oil;
the preparation method of the insecticidal composition comprises the following steps:
step 1: pouring the methyl esterified vegetable oil into a stirring kettle, sequentially adding the emulsifier, the emamectin benzoate, the dicyclopropyl grease, the organic soil and the antioxidant, and shearing and stirring for 30 minutes;
Step 2: and (3) performing serial sanding on the product obtained in the step (1) by using three sanding machines to prepare the suspending agent-state insecticidal composition consisting of 12% of emamectin benzoate and diproprionate.
when in use, 12 percent of emamectin benzoate and the dicyclopropyl grease suspending agent are diluted by 2000 times of water and sprayed for use, the pesticide has special effect on preventing whiteflies, and the preventing and treating effects of the pesticide for 1 day, 7 days and 15 days are respectively 92.4 percent, 96.6 percent and 98.3 percent. The pesticide is diluted 2500 times by using 5 percent of emamectin benzoate and dicyclopropanil single agent, and the control effect 1 day after the pesticide is used under the same condition is 78.2 percent and 58.9 percent respectively; the control effect 7 days after the pesticide is 64.6 percent and 89.6 percent respectively; the control effect 15 days after the pesticide is 56.3 percent and 81.9 percent respectively. The synergistic effect is very obvious after the emamectin benzoate and the dicyclopropanaplate insecticide are compounded, the control effect on the whitefly is greatly improved, and the timeliness and the persistence are both superior to those of a single agent.
In a fourth embodiment, an insecticidal composition comprises the following components: 3% of emamectin benzoate, 45% of dicyclopropanate, 2% of sodium dodecyl benzene sulfonate, 5% of NNO, 3% of polycarboxylate, 1% of antioxidant and the balance of corn starch;
The preparation method of the insecticidal composition comprises the following steps:
Step 1: respectively adding emamectin benzoate, dicyclopropyl tetramethrin, sodium dodecyl benzene sulfonate, NNO, polycarboxylate, antioxidant and corn starch into a mixing kettle, and mixing for 45 minutes;
step 2: performing jet milling on the product obtained in the step (1) by using a jet mill, and adding water for extrusion granulation;
And step 3: and (3) drying and screening the product obtained in the step (2) to obtain the water dispersible granule insecticidal composition consisting of 48% of emamectin benzoate and dicyclopropyl tetramat.
when in use, the water dispersible granule consisting of 48 percent of emamectin benzoate and dicyclopropanesefat is diluted by 10000 times of water and sprayed for use, and the control effect on the lesser leafhopper is special, and the control effect on 1 day, 7 days and 15 days after the application is respectively 95.3 percent, 100 percent and 99.3 percent. The single dose of 5 percent of emamectin benzoate and dicyclopropangolin is diluted by 2500 times and used under the same condition, and the control effect 1 day after the application is 52.3 percent and 84.6 percent respectively; the control effect 7 days after the pesticide is 75.4 percent and 90.6 percent respectively; the control effect 15 days after the pesticide is 52.3 percent and 84.6 percent respectively. It can be seen that the synergistic effect is very obvious after the emamectin benzoate and the dicyclopropanate are compounded, the control effect on the lesser leafhoppers is greatly improved, and the quick-acting property and the lasting property are both superior to those of a single agent.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
