Description
Technical Field
The invention relates to the technical field of pesticide adjuvants, and particularly provides a stable pesticide synergist and a preparation method thereof.
Background
The pesticide is vital to preventing and controlling diseases and pests and promoting the stable yield and high yield of grains and agriculture, but the excessive use of the pesticide not only increases the production cost, but also influences the quality safety of agricultural products and the safety of ecological environment. The improvement of the utilization rate of agricultural chemicals is a comprehensive research subject, and it is necessary to systematically research the improvement from a plurality of levels and angles. From the perspective of the use mode of the pesticide, the added tank-mixed synergist has an important effect on improving the pesticide effect and is an effective means for reducing and increasing the amount of the pesticide.
The mineral oil has a blocking effect on insect stomata, so that insects die by suffocation, and meanwhile, eggs can be directly killed by physical suffocation, and the lasting period is prolonged. In addition, the mineral oil is sprayed to seal the tentacles of adults and the tender tissues of plants, so that the male and female mating is influenced, and feeding parts and spawning places are difficult to find, thereby reducing the harm and spawning. The use of mineral oil in the control of plant diseases can destroy the cell walls of pathogens, interfere with their respiration, interfere with the attachment of pathogens to host plants, and also control mycelium growth, preventing spore germination and infection. Mineral oil is added in the herbicide control process, so that the fog drop drying time can be prolonged, and the absorption of liquid medicine is promoted.
Common mineral oils are mostly mixtures of paraffins (the main component being n-alkanes), cycloalkanes and aromatics, where paraffins are more insecticidally active than the other components and are safe for plants. Therefore, the lower the content of the aromatic hydrocarbon in the mineral oil, the better the insecticidal effect and the safer the crop. Mineral oil is insoluble in water, and an emulsifier is required to be added to emulsify the mineral oil into stable emulsion when the mineral oil is used, but due to the low HLB value of the mineral oil and the lack of a proper emulsifier, a product with qualified emulsion stability is difficult to develop.
With the technical progress and the great popularization of the plant protection unmanned aerial vehicle, specialized prevention and control organizations of China continuously emerge, the pesticide application area is rapidly increased, and 14 hundred million mu times of the unmanned aerial vehicle is broken through at present. The system control conforms to the development direction of modern agriculture, adapts to the regular change of diseases and pests, is an effective way for improving the working level of plant protection, and is an important measure for ensuring the safety of agricultural production, the quality safety of agricultural products and the agricultural ecological safety. The traditional mineral oil product has the defects of large operation area, large dosage and long service time (generally more than 4 h), and the stability requirement of the traditional prevention and control liquid medicine is difficult to meet due to the emulsion stability problem.
