Anti-photooxidation plant oil spray adjuvant used for insecticidal pesticide preparation and its use method

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...

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 effect is not as good as conventional antioxidants, so antioxidants such as TBHQ, BHT and BHA are still used in conventional vegetable oils (referring to document 6, "Effect of antioxidants on the oxidative stability of several cold-pressed vegetable oils" Journal of Henan University of Technology, Vol.33 No.3(2012) p.33-35)

At the same time, this patent uses the NPEO additive NP-10, which has more prominent ecological and environmental protection problems. The potential toxicity of this additive to the environment has been gradually confirmed, indicating that it is toxic and carcinogenic to mammals and aquatic organisms. And it has the effect of estrogen, which can easily cause the disorder and distortion of normal endocrine hormones in the human body. In some countries in Europe, its use has been clearly banned or restricted since 1976, and the limit is less than 0.1%.
