Control method for red palm weevil pests of palm plants

Abstract

The invention discloses a control method for red palm weevil pests of palm plants. The method comprises the following steps that A, a control agent I is prepared, specifically, dichlorvos emulsifiableconcentrates, omethoate emulsifiable concentrates, acephate emulsifiable concentrates and water are taken and are uniformly mixed so as to obtain the control agent I for later use; B, a control agentII is prepared, specifically, the dichlorvos emulsifiable concentrates, phoxim emulsifiable concentrates, the acephate emulsifiable concentrates and the water are taken and are uniformly mixed so asto obtain the control agent II for later use; and C, sprinkling irrigation is carried out, specifically, the control agent I or the control agent II is sprinkled onto interior leaves and leaf sheathsat the tops of the palm plants in spring, then the control agent I or the control agent I is sprinkled by adopting the same mode in the summer, the control agent is applied twice in each season, and the time interval for each application is 15-25 days. The method has the beneficial effects that the ratio of the control agent I to the control agent II is controlled, and plants and beneficial species cannot be damaged; and alternate sprinkling irrigation is adopted, so that the damage rate and the death rate of the palm plants are greatly decreased, in addition, the red palm weevil pests can also be prevented from generating the drug resistance, the damage rate of the plants is less than 5%, and the control effect reaches 86.59% or above.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a method for preventing and controlling the red palm weevil pest of the palm plant. Background technique [0002] Palm plants have become important garden plants in many urban areas in my country, and are an important part of urban greening and flower industry. The continuous spread of the red palm weevil epidemic has posed a serious threat to these plants. [0003] The red palm weevil has three generations in one year, and the times overlap. The optimum growth temperature is 24~28°C. When the temperature is lower than 14°C, the hatching rate of eggs is significantly reduced. Roots, stems and crowns are damaged, causing rapid necrosis of growth points. The harm is not easy to be found in the early stage, and it is already irreparable when it is found in the later stage. [0004] At present, the control method of chemical agents is mainly used, and a single pestic...

The harm is not easy to be found in the early stage, but it is already irreparable when it is found in the later stage

[0004] At present, the control method of chemical agents is mainly used, and a single pesticide is mainly used for spraying in different periods. The time of drug effect is short, the operation is complicated, and it consumes manpower and raw materials. It is easy to make the red palm weevil resistant to pesticides and the control effect is not good. , the stems are injected with high-toxin, high-residue and strong systemic pesticides for prevention and control, which is easy to damage the ecological environment and cause human and animal poisoning
