Problems solved by technology

The currently reported methods for preventing and controlling Spodoptera spp. mainly use organophosphorus pesticides such as phoxim and chlorpyrifos to spray or irrigate the roots. Although the dosage is large, the effect is often poor due to the influence of a large amount of residual wheat straw. , these organophosphate insecticides will aggravate the phytotoxicity of the herbicide nicosulfuron used in the same period on corn

example 1

[0018] Example 1: This trap consists of the following components: trichlorfon 9g, Spodoptera litura nuclear polyhedrosis virus preparation 3g (200 million PIB / ml), peanut oil 3g, edible essence 3g, fried wheat bran 40g, adsorption Sex carrier is 42g. The adsorptive carrier is a mixture of activated carbon powder and peat powder in a weight ratio of 1:1. It is prepared as follows:

[0019] Step 1: Grinding activated carbon powder and peat powder through a 30-mesh sieve, and mixing the two in a weight ratio of 1:1;

[0020] Step 2: Stir-fry the wheat bran, stir-fry the aroma; crush;

[0021] Step 3: Mix trichlorfon, emamectin benzoate, peanut oil, edible essence, fried wheat bran, and the mixture in step 1;

[0022] Step 4: slowly add water equivalent to 20% of the total weight of the mixture in step 3, and mix well;

[0023] Step 5: Use an extrusion granulator, granulate, take out, and dry to obtain the finished product of Example 1.

example 2

[0024] Example 2: Get trichlorfon 7.5g, emamectin benzoate 0.008g, Spodoptera litura nuclear polyhedrosis virus preparation 3g (200 million PIB / ml), peanut oil 3g, edible essence 3g, sauté 40g of wheat bran, the adsorptive carrier is 43.492g. The adsorptive carrier is a mixture of activated carbon powder and peat powder in a weight ratio of 1:1. The finished product of Example 2 was obtained according to the method of Example 1.

example 3

[0025] Example 3: get trichlorfon 6g, emamectin benzoate 0.016g, Spodoptera litura nucleopolyhedrosis virus preparation 3g (200 million PIB / ml), peanut oil 3g, edible essence 3g, fried fragrant 40g of wheat bran, 44.984g of adsorptive carrier. The adsorptive carrier is a mixture of activated carbon powder and peat powder in a weight ratio of 1:1. According to the method of embodiment 1, the finished product of example 3 is obtained.

Abstract

The invention relates to an attractant for preventing and controlling athetis lepigone and a preparation method of same. Each component of the attractant is readily available; the preparation method is practical, simple in process, convenient to operate, obvious in trapping effect and low in prevention and control cost; the trapping, prevention and control effects are excellent; and the attractant has better trapping effect compared with a single agent.

Description

technical field [0001] The invention relates to a trapping agent in the field of pesticides, in particular to a trapping agent for preventing and treating Spodoptera spp. and a preparation method thereof. Background technique [0002] In 2005, Athelis lepigone was first found to damage summer corn in Hebei Province, and gradually expanded its damage. More than 30 million mu occurred in Jiangsu and other places, becoming the main pest in today's production and seriously threatening the safety of food production. [0003] The adult moths like to move and lay eggs in hidden moist places, and the larvae also like to move in hidden moist places and harm crop seedlings. In recent years, mechanized wheat harvesting and stubble sowing of summer corn have been generally realized in the Huanghuaihai summer corn production areas, and the stalks after wheat harvesting are directly scattered to the fields, which provides a large area of ​​favorable conditions for the occurrence and dama...
