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 methods for preventing and controlling diseases and insects of farm crops, in particular to a method for preventing and controlling corn red spiders. The invention mainly aims to solve the technical problem of bad killing effect due to the fact that farmers cannot well master the best time for killing the red spiders. The method comprises the following steps of: 1, adding water into 5 to 10mm of pesticide to dilute the pesticide by 1,500 to 2,000 folds; 2, spraying1 to 3 parts of the diluted pesticide in farmlands before sowing in spring when the temperature rises to between 10 and 12 DEG C; 3, when the corn plants grow 65 to 80 centimeter high, and spraying the whole corn plants by using 1 to 3 parts of the diluted pesticide; and 4, spraying the whole corn plants again 3 to 4 days after the spraying of the whole corn plants by the step 3. The method has the advantages that: the damages of the red spiders to the corns can be effectively eliminated, the red spiders waken up from hibernation can be killed by the primary spraying, and the red spiders are prevented from laying eggs; and by the whole-plant spraying, the red spiders not killed by the primary spraying can be killed, so that after twice sprayings, the damages of the red spiders to the corns can be effectively prevented.

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...
