Embodiment approach

[0027] As a particularly preferred embodiment of the present invention, the content of the pesticide active ingredient in the pesticide preparation is 0.1-10% by weight, the content of the conduction enhancer is 0.01-8% by weight, and the content of the surfactant is 1-20% by weight, the content of the sustained-release agent is 1-20% by weight, and the solvent is supplemented to 100% by weight. In the case of this preferred embodiment, the pesticide composition can achieve a very prominent synergistic effect and exhibit high control activity against various diseases and insect pests.

[0028]According to the first aspect of the present invention, there are no special requirements on the components of the auxiliary agent in the injection composition, and materials commonly used in this field can be used, for example: the conduction enhancer is selected from glycyrrhizic acid, azone, thiophene, etc. Ketone, polyoxyalkylene modified polymethicone, dimethicone copolyol, 2-(3-hydr...

Abstract

The invention discloses an injection composition for preventing and treating Korean pine cone pests and application of the injection composition. The injection composition contains active ingredients,namely, chlorfenapyr and dinotefuran dextro-enantiomer, and the weight ratio of chlorfenapyr to dinotefuran dextro-enantiomer is 1: (0.01-99). Compared with the single use of chlorfenapyr and dinotefuran dextro-enantiomer, the injection composition has a better control effect on forestry pests. In addition, chlorfenapyr and dinotefuran dextro-enantiomer have a synergistic effect in a wide range of use ratio. The injection composition is reasonable in component and good in prevention and treatment effect, has a very remarkable prevention and treatment effect on mixed occurrence of different types of Korean pine cone pests, and is high in action speed, high in pesticide utilization rate, capable of saving cost and high in safety. Meanwhile, various different types of mixed or successive Korean pine cone insect pests can be effectively prevented and treated, so that the use of pesticides is reduced, and the pollution to the environment is reduced; and korean pine health, under-forest updating of Korean pine seedlings and the yield and quality of Korean pine seeds are improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an injection composition for preventing and controlling the cone pests of Korean pine and its application. Background technique [0002] Korean pine is the dominant tree species of natural forests in Northeast my country. It is not only a precious timber species, but also one of the main tree species for afforestation. At the same time, Korean pine nuts are rich in oil and protein, and are deeply loved by domestic and foreign consumers because of their extremely high nutritional and health value. It is also one of the important driving forces for the rapid development of the forestry industry. However, in recent years, with the increase in the area of ​​Korean pine plantations and the intensification of human activities such as picking cones, the original ecological balance has been broken, resulting in frequent occurrence of Korean pine pests and diseases, especially the ram...
