Embodiment 1

[0021] A control method for the star anise leaf beetle, comprising the steps of:

[0022] (1) On November 15, 2016, dig a ring ditch under the star anise tree, with a depth of 25-30cm, sprinkle 20% Sophora japonica total alkali medicinal fertilizer granules at a rate of 1kg / tree, cover with soil, and fully water;

[0023] (2) On March 27 and July 25 of the second year, spray 2.5% rotenone hot fog with a hot fog machine. % Rotenone hot spray and water are mixed at a ratio of 3:1, the dosage per mu is 500ml, and the prepared mixture is evenly sprayed into the star anise trees. On March 27 and July 25, before 4-8 am or after 5 pm, spray pesticides when there is no wind or below level 3 wind.

[0024] 24h and 48h after spraying, the control effect was investigated. The conventional spray was used in the control field. The conventional spraying agent was 2.5% Kungfu EC mixed with water 1000 times + 3.2% Abamectin EC mixed with water 1000 times.

Abstract

The invention discloses a prevention and treatment method for Oides duporti. According to the invention, through circulating application of a pesticidal fertilizer in November to December, the incubation rate of Oides duporti ova and the pupation rate of Oides duporti pupae are reduced, and the initial population number of the Oides duporti in a field is decreased; and by adoption of a hot smog method in a full outbreak period in March to April and July to August, pesticide smog with high concentration and high density is utilized for long-term enshrouding treatment, so Oides duporti larvae and adult Oides duporti are difficult to hide, wherein the prevention and treatment effects with 95% or above can be reached through treatment for two times.

Description

technical field [0001] The invention belongs to the field of pesticide prevention and control, and in particular relates to a method for prevention and treatment of star anise anthracnose.
