Blueberry anoplophora chinensis prevention and control method

Abstract

In order to overcome defects in the prior art, the invention provides a blueberry anoplophora chinensis prevention and control method which comprises the following steps: (1) performing root irrigation prevention and control on a single blueberry plant by adopting a compound solution A in a first time period; (2) manually capturing imagoes in a second time period; (3) in a third time period, performing root irrigation prevention and control by adopting the compound solution A; and (4) in a fourth time period, injecting a compound solution B into excrement discharge holes of anoplophora chinensis larvae for prevention and control, wherein the compound solution A comprises matrine, pyrethrin, azadirachtin and alcohol in a formula ratio, and the compound solution B comprises matrine and alcohol in a formula ratio. By means of the method, the rate of plants with anoplophora chinensis can be reduced to 1.2% at present from original 11.5%, the yield of blueberries is increased by 20% or above, and direct economic loss is reduced by 12.5 thousand yuan / mu or above.

Description

technical field [0001] The invention belongs to the technical field of fruit planting technology, and in particular relates to a method for preventing and treating the blueberry longhorn beetle. Background technique [0002] Blueberry is a new fruit tree that has been planted on a large scale in recent years. Compared with other fruit trees, there are fewer pests. Beetle damage increases year by year. The range of moth damage by star beetles is generally within 15 cm on the ground. If it encounters the root, it will go down along the root, which can reach a depth of more than 30 cm. The tree dies. [0003] Existing chemical control methods for longhorn beetles include: digging out larvae with wire, injecting, inserting slices, plugging holes, inserting bottles (transfusion), etc. The methods are basically the same, and all need to dig out the wood chips that block the holes, and then insert poisonous slices or inject drugs , Stuffed cotton balls with medicine, etc. On ...

AI Technical Summary

Problems solved by technology

[0005] (1) Manual digging or drilling with an electric drill is required, and the labor cost is high. At the same time, the chemicals (chemical pesticides such as lambda-cyhalothrin, thiacloprid, and dichlorvos) used in traditional star beetle control are not suitable for green food and organic food production regulations, not applicable to organic blueberry production

[0006] (2) The sex attractants of longicorn beetles are highly specific. The sex attractants of different types of longicorn beetles are different, and the attractant effects of the same type of longicorn beetle sex attractants in different regions are also different, and they are only for adults, and the field lure effect is not obvious , there are still a large number of beetles mating and laying eggs in the park, which continue to endanger the roots of blueberry trees

[0007] (3) Natural enemies (Velvet beetle, swollen-legged wasp, etc.) are mainly cultivated in the laboratory, and they need to adapt to the wild environment after release. If the parasitism cannot be completed in the first time, it is difficult to guarantee their own survival, and the effect is slow and cannot be guaranteed. Effective control effect

[0008] (4) Bio-control bacteria control (Beauveria bassiana, Metarhizium anisopliae, etc.) During the process of using Beauveria bassiana to control long-beetle larvae in the park, it was found that Beauveria bassiana can complete the work of beetle larvae infection, but due to the field expansion of Beauveria bassiana and the The use time is relatively strict to achieve the ideal control effect, and the cost of use is high, so it is impossible to carry out large-scale control

[0010] Therefore, the traditional method of controlling long beetle is not suitable for large-scale organic blueberry production requirements
