Embodiment 1

[0014] A kind of corn red spider control method in the present embodiment, its steps are as follows:

[0015] 1) Take 5 ml of 1.8% Abamectin and dilute it 1500 times with water;

[0016] 2) Take 1 portion of diluted avermectin, and spray the farmland at 12:00 when the temperature rises to 10°C before sowing in spring;

[0017] 3) When the corn plant grows to a height of 65 cm, at 7:00, take 1 part of diluted abamectin and spray the whole plant of the corn plant;

[0018] 4) After step (3) spraying the whole plant for 3 days, spray the whole plant again.

Embodiment 2

[0020] A kind of corn red spider control method in the present embodiment, its steps are as follows:

[0021] 1) Take 7 ml of 20% pyridaben emulsifiable concentrate and dilute it 1800 times with water;

[0022] 2) Take 2 parts of diluted pyridaben EC, and spray the farmland at 16:00 when the temperature rises to 11°C before sowing in spring;

[0023] 3) When the corn plant grows to a height of 70 cm, at 10:00, take 2 parts of diluted pyridaben emulsifiable oil and spray the whole plant of the corn plant;

[0024] 4) After 4 days of spraying the whole plant in step (3), spray the whole plant again.

Embodiment 3

[0026] A kind of corn red spider control method in the present embodiment, its steps are as follows:

[0027] 1) Take 7 milliliters of a mixture of acaricide and diesel oil with a weight ratio of 1:0.8, and dilute it 2000 times with water;

[0028] 2) Take 3 parts of the diluted mixture, and spray the farmland at 14:00 when the temperature rises to 12°C before sowing in spring;

[0029] 3) When the corn plant grows to a height of 75 centimeters, at 16:00, take 3 parts of the diluted mixture and spray the whole plant of the corn plant;

[0030] 4) After step (3) spraying the whole plant for 3 days, spray the whole plant again.

Abstract

The invention relates to the technical field of crop pest control methods, in particular to a control method of a corn red spider. The technical problem of unobvious killing effect due to the fact that farmers cannot well master the best time for killing the red spider is solved. The control method comprises the following steps that (1) 5 to 10 milliliters of pesticide is taken, and water is addedto dilute 1500 to 2000 times; (2) 1 to 3 parts of the diluted pesticide are taken, and when the temperature rises to 10 to 12 DEG C before sowing is carried out in spring, farmland is sprayed;(3) when corn plants grow to 65-80cm high, 1-3 parts of the diluted pesticide are taken to spray the corn plants in a whole-crop mode; and (4) after whole-crop spaying in the step (3) is carried out for 3-4days, and whole-crop spaying is carried out again. The control method can effectively kill the harm of the red spider to the corn, and the first spraying can kill the red spider newly unearthed from hibernation to prevent the red spider from laying eggs; the whole-crop spaying can kill the red spider which is not killed, and the damage of the red spider to the corn is effectively prevented throughtwo times of spraying.

Description

technical field [0001] The invention relates to the technical field of a method for preventing and controlling crop production diseases and insect pests, in particular to a method for preventing and controlling corn red spiders. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy. However, in recent years, with the development of the economy, the area of ​​agricultural land has been decreasing, and it is imperative to increase food production. Corn plays a pivotal role in my country's crop production and is widely used as feed raw material and industrial raw material for consumption. Corn is rich in nutrients necessary for the growth of various livestock and poultry, and is the most important raw material for feed. Corn is also the food variety with the most follow-up products. The deep processing industry using corn as raw material is called "sunrise industry" and "gold industry". With the co...
