Composition and method used for preventing and killing grapholitha molesta

Abstract

The invention relates to a composition used for preventing and killing grapholitha molesta. The composition contains 1 to 20% of fenoxycarb, 1 to 20% of diflubenzuron, 1 to 20% of celangulin, and 0.1 to 1% of hendecanol. The composition is used for preventing and killing grapholitha molesta, and effect is excellent.

Description

Technical field: [0001] The invention belongs to the field of prevention and control of fruit tree diseases and insect pests, and in particular relates to a composition and a method for preventing and treating the small pear borer. technical background: [0002] The small pear borer, also known as the small pear fruit moth, the pear jelly borer, the peach breaker, or the oriental fruit moth, is called pear for short, belongs to the Lepidoptera, and is a worldwide fruit-boring pest. Boring damages host fruit and is widely distributed in Asia, Europe, America, and Australia. It is one of the main pests in orchards. Its feeding habits can harm peaches, apples, pears, apricots, loquats, papaya and other fruit trees. Pear borer larvae in the peach orchard mainly damage the shoots in spring, damage the shoots and peach fruits in summer, and move to apple orchards and pear orchards in autumn to damage fruits. Harm the young shoots, cause the death of the young shoots, and affect t...

Problems solved by technology

[0003] In the prior art, using sexual attractants to interfere with mating to prevent large-scale pear borer moths is a widely used method, but the pear borers trapped by sexual attractants are mainly males, as long as the number of males in a population is not less than a certain The threshold value may not affect the rapid development of the population. Therefore, in the practice of using sexual attractants to control pear smallness, the attractants or traps must reach a certain density to have a good effect, and the sexual attractants are easily oxidized and Decomposition, which will increase the cost of control inputs, and the effect will be slow

[0004] The use of chemical pesticides to control pear borer is also a common method in agricultural practice. However, due to its boring characteristics, once the larvae get into the young shoots and fruits, chemical pesticides cannot play a good control effect.

In addition, the long-term use of pesticides not only accelerates the development of pest resistance and increases the amount of pesticides used, but also kills natural enemies, pollutes the ecological environment, and leads to excessive pesticide residues in fruits.
