Preventing method of long-horned beetles on roses

Abstract

The invention discloses a preventing method of long-horned beetles on roses. The method particularly includes the following steps of (1) electric drill trepanning, wherein whether or not saw dust discharged by the long-horned beetles exist in the roots of the roses is inspected, for plants with the saw dust observed, a rechargeable handheld electric drill is adopted, declivitous drilling is conducted on the roots of the roses in the positions of the saw dust, the bore diameter is 3-5 mm, and the depth is 10 cm; (2) liquid medicine injection, wherein a pesticide is contained in a bottle of a long-horned beetle preventing machine after being diluted 200 times, 10-20 ml of the pesticide is injected into drilling holes through a nozzle of the long-horned beetle preventing machine; (3) sealing, wherein a brush is dipped into moderate emulsion paint, the drilling holes after liquid medicine injection is painted with the emulsion paint, and hole openings are sealed; (4) effect observation and secondary preventing, wherein one week after sealing, it is investigated that whether or not fresh saw dust exists, and if yes, according to the above technology, operation is conducted again for preventing. By means of the method, feed liquid of the pesticide can be accurately applied onto pest positions, so that liquid medicine can reach sick targets fast, operation is simple, use is convenient, and pesticide residues caused by large-scale medicine applying are avoided.

Description

technical field [0001] The invention belongs to the technical field of plant control methods, and in particular relates to a control method for rose beetle. Background technique [0002] Beetle is an important stem-boring pest of roses. It uses larvae to bore into the trunk and roots of roses, and feeds on the base, causing the plants to weaken and eventually cause the entire plant to die. If it is not prevented in time, it can lead to the death of a large area of ​​roses, until the garden is destroyed, which has caused a devastating blow to the production of roses. [0003] Currently, there are few reported methods for controlling rose beetle. Some people release Scleroderma guani parasitic longhorn beetle in the rose field for control, but the effect of this method is slow, and the effect is greatly affected by climate, natural enemies and placement distance. [0004] At present, there are companies that have developed special commodities for the prevention and treatment...

AI Technical Summary

Problems solved by technology

However, roses are bushes with dense thorns, and it is difficult to find boreholes, and it is difficult to clean boreholes, and it is impossible to pour pesticides, so it is basically impossible to use this kind of control for prevention and treatment.
