Coconut oil agricultural synergistic agent capable of killing pest mites as well as preparation method and application

Abstract

The invention discloses a coconut oil agricultural synergistic agent capable of killing pest mites. The coconut oil agricultural synergistic agent capable of killing pest mites is prepared from the following components in parts by weight: 2 to 9 parts of coconut oil, 2 to 4 parts of fatty alcohol-polyoxyethylene ether and 0.5 to 5 parts of organic modified polysiloxane. The invention further discloses application of the coconut oil agricultural synergistic agent to killing of the pest mites. The coconut oil agricultural synergistic agent provided by the invention has the effects of dissolvinga pest mite wax layer and sealing an pest mite spiracles; has extremely low surface tension, better wettability, adhesiveness, expansibility and permeability, is suitable for using by combining with an insecticide, a fungicide, a herbicide and a foliar fertilizer, can be used as a special synergistic agent for aerial crop protection or ultra-low solubility spraying, and has the effects of thickening the wax layer of crop leaves, making the crop leaves lustrous and glossy, and effectively inhibiting moss and sooty mould.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a coconut oil agricultural synergist for killing mites and its preparation method and application. Background technique [0002] Mites cause huge economic losses to our country's agriculture. There are two main ways to control pest mites in my country: chemical agent control and mineral oil control. Commonly used chemical agents include abamectin, pyridaben, spirodiclofen, spirotetramat, bifenazate and etoxazole, etc. The large-scale use of these chemical agents has caused great harm to the ecological environment, such as pollution The water source and pesticide residues exceed the standard, which increases the resistance of pest mites and the cost of pesticides for farmers. At present, an important way to control pest mites is to use mineral oil. Because it has a good effect of closing the spiracle of pest mites, it causes mechanical suffocation of pest mites. No resistance, no toxi...

Commonly used chemical agents include abamectin, pyridaben, spirodiclofen, spirotetramat, bifenazate and etoxazole, etc. The large-scale use of these chemical agents has caused great harm to the ecological environment, such as pollution The water source and pesticide residues exceed the standard, which increases the resistance of pest mites and the cost of pesticides for farmers. At present, an important way to control pest mites is to use mineral oil. Because it has a good effect of closing the spiracle of pest mites, it causes mechanical suffocation of pest mites. No resistance, no toxicity, but there are many disadvantages: because mineral oil is extracted from petroleum, after spraying on the leaves, the plants cannot absorb and convert it into plant nutrients, but instead pollute the leaves and fruit surfaces; It can not be used under the environment, and it is easy to burn the leaves and fruit surfaces; the miscibility of mineral oil is not good, and it cannot be mixed with many insecticides and fungicides, otherwise, flocculation is easy to occur, and it is easy to cause phytotoxicity
