Problems solved by technology

However, as far as the applicant is aware, there is no research on the use of methylated vegetable oil as a spray adjuvant for insecticidal pesticide formulations
[0004] In addition, vegetable oils will undergo a series of chemical changes during storage at room temperature, which will cause the product to become darker in color, produce bad odor, and be easily oxidized automatically, resulting in product instability (see Document 5, "Oxidative stability of different edible vegetable oils Sexual research "China Oils and Fats, Vol.34 No.2(2009) p.31-34), the applicant found a Chinese invention patent application with application number CN201110294264.9 and publication number CN102511476A (name: a spray additive and In its preparation method), the ultraviolet absorber UV-P has been adopted to prevent vegetable oil from being oxidized by ultraviolet photolysis, but its eff

Embodiment 1

[0031] Example 1 Detection of wettability improvement

[0032] Wetting properties of water and common pesticide preparations (36% monosultap SP, 2% abamectin EC, 70% imidacloprid WDG) on rice and wheat leaves before and after adding the adjuvants of the present invention were tested. Note: SP is soluble powder, EC is emulsifiable concentrate, WDG is water dispersible granule, the same below.

[0033] When testing, firstly dilute the pesticide preparation with water, then add the spray auxiliaries of cases 1, 2, and 3 respectively, stir well and then test. The mass ratio of the adjuvant to the diluted pesticide solution is 15%.

[0034]The results are shown in Table 4, showing that the adjuvant of the present invention can significantly improve the wetting performance of water and common pesticide preparations (36% monosultap SP, 2% abamectin EC, 70% imidacloprid WDG) on rice and wheat leaves .

[0036]

Embodiment 2

[0037] Example 2 Maximum Stable Retention Improvement Detection

[0038] Using the dipping method, the commonly used pesticide preparations (36% monosultap SP, 2% avermectin EC, 70% imidacloprid WDG) were detected on the leaves of target plants (rice, wheat and cabbage) before and after adding the adjuvant of the present invention. Maximum stable retention (three parallel experiments).

[0039] When testing, firstly dilute the pesticide preparation with water, then add the spray auxiliaries of cases 1, 2, and 3 respectively, stir well and then test. The mass ratio of the adjuvant to the diluted pesticide solution is 15%.

[0040] The results are shown in Table 5 to Table 7, showing that the adjuvant of the present invention can significantly increase the effect of commonly used pesticide preparations (36% monosultap SP, 2% abamectin EC, 70% imidacloprid WDG) on target plants (rice, wheat and Cabbage) maximum stable retention on leaves.

Embodiment 3

[0048] Example 3 Detection of 2% Abamectin EC efficacy improvement

[0049] Detect the drug effect of 2% avermectin EC on rice leaf roller before and after adding the auxiliary agent of the present invention.

[0050] When testing, firstly dilute the pesticide preparation with water, then add the spray auxiliaries of cases 1 and 4 respectively, stir well and then test. The mass ratio of the adjuvant to the diluted pesticide solution is 15%.

[0051] The results are shown in Table 8, indicating that the adjuvant of the present invention can significantly improve the control effect of 2% abamectin EC on rice leaf rollers under the premise of appropriately reducing the use of pesticide preparations.

Abstract

The invention relates to an anti-photooxidation plant oil spray adjuvant used for an insecticidal pesticide preparation and its use method. The adjuvant comprises the following components by weight: 3%-9% of a wetting agent; 6%-12% of fatty alcohol-polyoxyethylene ether O-10; 0.2%-2% of an antioxidant; 2%-5% of a penetrating agent; and the balance methyl esterified plant oil. The use method includes: firstly diluting a to-be-sprayed pesticide solution with water, then adding the spray adjuvant, stirring them uniformly, and then spraying the mixture to a target plant by a sprayer. The adjuvant can be added directly into a well diluted pesticide preparation solution in the field so as to increase the wettability and retention capacity of the pesticide solution, thus improving efficacy.

Description

technical field [0001] The present invention relates to a pesticide spraying auxiliary and its use method, in particular to an anti-photooxidation plant oil spraying auxiliary for insecticidal pesticide preparations and its use method, which can make the pesticide preparation liquid wet and spread on the plant leaves. The cloth can increase the holding capacity and belongs to the technical field of pesticide adjuvants. Background technique [0002] The occurrence and damage of crop diseases and insect pests in farmland lead to the reduction of crop yield. So far, chemical control is still the main means of pest control and yield protection. However, there are many types of chemical pesticides at this stage, and the frequency of application has also increased. The moment the liquid medicine is sprayed by the spraying device and contacts the surface of the target plant leaves, its dynamic surface tension is high, and it is easy to bounce or roll off the target plant. It is di...
