Pesticide used for preventing and treating rot disease of fruit trees and production method thereof

Abstract

The invention discloses a pesticide used for preventing and treating the rot disease of fruit trees. The pesticide is prepared from the following raw materials by weight: 10 to 12 parts of pre-fractionation oil, 10 to 20 parts of light oil, 10 to 15 parts of a pesticide emulsifier, 5 to 10 parts of copper sulphate, 10 to 15 parts of kerosene, 5 to 10 parts of zinc sulfate, 10 to 15 parts of ammonium molybdate, 5 to 10 parts of a binder and 20 to 30 parts of water. The pesticide provided by the invention can kill and inhibit fruit tree rot disease germs, effectively infiltrate into the inner layers of fruit tree barks, form an effective water-proof protective layer on the surface and a protective film on wounds of the barks and effectively resist attack by outside germs. The pesticide can resist washing by heavy rain; the drug effect of the pesticide lasts for more than 50 d; and the pesticide has a rot disease germ inhibition rate of more than 90%, can substantially reduce influence of residual on fruit and pollution to the environment and is a nontoxic, nuisanceless and novel pesticide.

Description

technical field [0001] The invention relates to a pesticide and a production method thereof, in particular to a pesticide for preventing and treating fruit tree rot and a production method thereof. Background technique [0002] Commonly known as "fruit tree cancer", rot is a malignant disease of branches that seriously threatens the normal growth and fruiting life of fruit trees, especially in old orchards and canopy-closed orchards, and spreads very quickly. At present, the effective pesticide for preventing and treating fruit tree rot is made of powder non-metallic oxide-arsenic oxide as the main component. This type of pesticide has the following defects: one is that the arsenic pesticide has high toxicity and high residue, so it has been listed as a restricted product by the Ministry of Agriculture; It has a killing effect, but it is basically difficult to penetrate below the skin of the branches; the third is that its adhesion is poor, and it is easy to fall off after ...

Problems solved by technology

This type of pesticide has the following defects: one is that the arsenic pesticide has high toxicity and high residue, so it has been listed as a restricted product by the Ministry of Agriculture; It has a killing effect, but it is basically difficult to penetrate below the skin of the branches; the third is that its adhesion is poor, and it is easy to fall off after being washed by rain

However, due to the poor adhesion and lack of sealability of industrial permeation aids, this has led to the following disadvantages: one is that it is easy to fall off after being washed by rainwater; intrusion

The majority of fruit farmers try to mix mineral oil such as diesel oil into the arsenic oxide pesticides, which improves the penetration and sealing properties of the pesticides to a certain extent, but it is very easy to "burn" the branches of fruit trees
