Due to the increasing adaptability and resistance of pests, the single use of pest control in agricultural production is usually not effective. The combination of drugs has become a common method for dealing with pests. The following are some of the more difficult to treat pests commonly found on fruit trees and vegetables. The summary is as follows, I hope to help everyone.
Taoyuan
Taotao has a good governance, but also refractory. The effective method is to use a mixture of imidacloprid, acetamiprid, pymetrozine, and nitenpyram, which are basically difficult to work. One is the cause of aphid resistance, and the other is other physical reasons. These two well-validated formulas can be tried: one is avermectin + nitenpyram + pymetrozine; the other is Cis-cypermethrin + pymetrozine + imidacloprid.
Kang's whitefly
Kang's whitefly occurs in apples, pears, peaches, and even grapes. It is harmful and can cause diseases such as coal pollution and soot. After killing phosphorus, it is forbidden to use it on fruit trees. It is chlorpyrifos instead of killing phosphorus. The effect is better than killing phosphorus, and the fruit trees such as pear trees will appear to fall.
At present, there is no specific medicine, and the compounding can be used: chlorpyrifos, buprofezin, pyriproxyfen, fenvalerate, malathion, etc., and mixed with spirotetramat and thiamethoxam, the effects are similar.
Heartworm
All kinds of heartworms, peach, peach, apple, apple, pear, pear, etc., before the drill collar, with the use of pyrethroids with a vitamin salt, can not prevent. It is not very easy to use a variety of Kang Kuan products.
Two good single-agent products are recommended: insecticide, fipronil, although fipronil is prohibited from spraying, but the orchard has no bees and can be used.
Pear and Tenebrio
Pear saplings are controlled with avermectin and spirotetramat, and avermectin is resistant. Basically, even farmers know it, but the resistance of spirotetramat is produced, which may not be noticed by many people.
At present, there is no way to replace spirotetramat, and continue to use it. Tenebrio molitor has increased resistance to imidacloprid, and pymetrozine and thiamethoxam have good effects.
Grape green scorpion
The green blind owl loves to damage the young leaves, young shoots and young fruit. The grape granules that have been licked by it are basically abolished, so the prevention and control of the leaf-leaf stage is particularly important. Various fipronil, microemulsions, suspension seed coatings, and fipronil are more desirable for the control of green blind mites.
Mango thrips
Hummer is really difficult to cure, use ethyl spinosad, there is no good product at present.
Moss
Oxime, snail ester, and alkyne are used in sputum, and the amount of greenhouses and fruit trees is too small to be cured.
Whitefly
Whitefly is a disease of vegetables and spreads viral diseases. Spraying should be combined with warming or smoky combination.
Polyethylene anticorrosive adhesive outer tape and polyethylene anticorrosive inner tape belt, polyethylene anticorrosive patch and anticorrosive primer together form polyethylene cold tape anticorrosive system. The polythene anticorrosive adhesive outer tape has the thicker base film and thin film, which mainly protects the corrosion and becomes a protective belt.
