Prevention and control method of panonychus ulmi and application

An apple pan-claw mites and equation technology, applied in application, botanical equipment and methods, animal repellents, etc., can solve the problem of judging simple control indicators of apple pan-claw mites, practical application for technicians and fruit farmers, and apple whole-claw mites. To solve the problems of low efficiency of claw mites prevention and control, it can reduce the phenomenon of missed inspection and false inspection, ensure scientificity and practicability, and reduce the workload of investigation.

Problems solved by technology

[0007] (1) In the actual operation process, the existing apple claw mite control indicators are cumbersome to investigate, difficult to grasp, and take a long time to investigate, and are prone to missed and wrong investigations. It is difficult for technicians and fruit growers to apply them in practice. The application penetration rate is low, and empirical medication is still used
[0008] (2) There are differences in the living habits and fecundity of Panonychus and Tetranychus hawthorn in apples, and the distribut

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038]Aiming at the problems existing in the prior art, the present invention provides a control method and application of Panonychus apple. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] like figure 1 As shown, the prevention and control method of the apple panonychia provided by the embodiments of the present invention may further comprise the steps:

[0040] S101, through the field survey of Panonychus apple, record the proportion of leaves with mite survival.

[0041] S102, based on the field investigation results obtained in S101, according to the resul...

Abstract

The invention belongs to the technical field of pest and disease control, and discloses a prevention and control method of panonychus ulmi and application. The prevention and control method includes the steps that after the number of panonychus ulmi of all leaves is recorded through field investigation of the panonychus ulmi, the average each-leaf panonychus ulmi amount is calculated, meanwhile, the panonychus ulmi-leaf rate is investigated, and the proportion of the leaves where the panonychus ulmi survives is calculated; based on a field investigation result, a relationship model of the panonychus ulmi-leaf rate, the average each-leaf panonychus ulmi amount and the field damage level is established; and the prevention and control effect of common acaricide is evaluated and actual prevention and control indexes are verified through field efficacy tests. By recording the number of panonychus ulmi on all leaves, the average each-leaf panonychus ulmi amount is calculated, meanwhile, thepanonychus ulmi-leaf rate is investigated, the proporton of tree leaves where the panonychus ulmi survives is calculated, the investigation workload is greatly reduced, a relation model of the panonychus ulmi-leaf rate, the average each-leaf panonychus ulmi amount and the field damage level is established on the basis of a large number of investigation results, actual verification is conducted through a field pesticide effect test, scientificity and the practicability of simplified prevention and control indexes of the panonychus ulmi are ensured, and the prevention and control period of the panonychus ulmi can be rapidly, simply and conveniently determined.

Description

technical field [0001] The invention belongs to the technical field of disease and insect pest control, and in particular relates to a control method and application of Panonychus apple. Background technique [0002] At present, the apple claw mite Panonychus ulmi (Koch), belongs to the order Acarina, Tetranychusidae, also known as the apple spider mite. It is mainly distributed in Liaoning, Shandong, Shanxi, Henan, Hebei, Jiangsu, Hubei, Sichuan, Shaanxi, Gansu, Ningxia, Inner Mongolia, Beijing and other provinces (regions, cities) in China. The main hosts are apples, pears, peaches, plums, apricots, hawthorns, sago, crabapple, cherries and ornamental plants such as cherry blossoms and roses. Small chlorotic spots appear on leaves at the initial stage of damage, and later many spots are connected into plaques. Severely damaged leaves are scorched and burnt, and leaves fall early. [0003] Pest mites have become the most common control object in orchards everywhere. Acari...
