Embodiment 1

[0026] A control method for sugarcane tooth edge beetles, comprising the following steps:

[0027] 1. Determine the application period.

[0028] After the sugarcane was planted, between April and June, 20W black light was used to lure adult beetle beetles, and the date when the number of beetle beetle adults reached the peak was obtained. The specific data are shown in the table below.

[0029] Table 1. The number of adult beetles attracted by black light

[0030]

[0031]

[0032] According to the dynamic change of the number of adults fluttering lights, the peak date is obtained from the gradual increase to the high point with a downward trend. In this embodiment, the date when the adult number of beetles reached the peak is around May 21 and May 22. Apply 7-15 days after that date, approximately between May 29 and June 5.

[0033] 2. Application method.

[0034] After determining the application period, mix imidacloprid granules with a mass percentage of 2% and fer...

Embodiment 2

[0041] A control method for sugarcane tooth edge beetles, comprising the following steps:

[0042] 1. Determine the application period.

[0043]After planting sugarcane, between April and June, use 40W black light to lure adult beetle beetles, and get the date when the number of beetle adults reaches the peak, which can be gradually increased according to the dynamic changes in the number of adults fluttering on the lamp. The downward trend results in a peak date, after which date the application is carried out 7-15 days, cf. Example 1.

[0044] 2. Application method.

[0045] After the application period is determined, the first soil cultivation is carried out at the base of the sugarcane, and the depth of the soil cultivation is 25-30cm; then the imidacloprid mass percentage content of 2% granules and fertilizers are evenly mixed, and the radius of the sugarcane base is 10 cm. In the range of -20cm, spray according to the amount of 3-5kg granules per mu, and then carry out...

Embodiment 3

[0051] A control method for sugarcane tooth edge beetles, comprising the following steps:

[0052] 1. Determine the application period.

[0053] After planting sugarcane, between April and June, use 20W black light to lure adult beetle beetles, and get the date when the number of beetle adults reaches the peak, which can be gradually increased according to the dynamic changes in the number of adults fluttering on the lamp. The downward trend results in a peak date, after which date the application is carried out 7-15 days, cf. Example 1.

[0054] 2. Application method.

[0055] After determining the application period, mix the phoxim granule with a mass percentage of 3% and the fertilizer evenly, and spread it within the radius of 10-20cm at the base of the sugarcane, according to the amount of 3-5kg granule per mu. Apply pesticides, and then carry out soil cultivation, and the depth of soil cultivation is 5-15cm. The experiment adopts random block arrangement method. The ...

Abstract

The present invention relates to a sugarcane exolontha serrulata gyllenhall control method, and belongs to the technical field of pest control. The control method comprises the following steps of broadcasting a pesticide formulation for killing exolontha serrulata gyllenhalls at roots of sugarcanes at a pesticide application period from May to August after the sugarcanes are planted, and then earthing up, the earth-up depth being 5-15 cm. According to biological characteristics of the exolontha serrulata gyllenhalls, pesticides are applied at the most sensitive period of the exolontha serrulata gyllenhalls and are applied within activity layers of the pests, thereby enabling the pests to be easy to contact the pesticides, fully playing the effect of the pesticides and raising the control effect; and with adoption of the control method, damages caused by the exolontha serrulata gyllenhalls can be effectively controlled by one-time pesticides application, and the method has excellent control effects.

Description

technical field [0001] The invention relates to a method for controlling pests, in particular to a method for controlling sugarcane beetles. Background technique [0002] The toothed beetle (Exolontha serrulata Gyllenhall) belongs to the order Coleoptera, and belongs to the branchia family. The insect is widely distributed in sugarcane areas such as Guangdong, Guangxi, Yunnan, and Hainan, and is one of the main beetle species in sugarcane areas in South China. The toothed beetle kills cane roots and heads with larvae (grubs). Due to the large body of beetle beetle larvae and the large amount of food they eat, the underground stems of the damaged sugarcane are often cut off or bored into holes, and the roots of the sugarcane are eaten up. Sugarcane damage generally reduces yield by 15t / hm 2 Around 30-45t / hm2 of sugarcane fields that were severely damaged 2 . In addition to the loss of yield, the damage of beetles also affects the quality of sugarcane, resulting in a decr...
