Abstract

The invention discloses an agricultural control method for red spiders in peanut fields. Washing the plants by a water pump; the washing direction is as follows: washing the plant from the root of the plant to the upper direction; the time of the scouring is as follows: the number of red spiders was observed visually at 25-30 heads/strain. In the technical scheme, drought is used as a condition for red spiders to break out, the red spiders existing on the plants can be washed away in a plant washing mode, meanwhile, drought resisting operation can be performed, and the operation cost is effectively reduced in a drought resisting and insect killing combined mode; in addition, the method is also suitable for red spider control of cotton seedlings, soybean seedlings or other plants planted in dry land.

Description

Agricultural control method for red spiders in peanut field

Technical Field

The invention belongs to the field of agricultural control, and particularly relates to an agricultural control method for red spiders in peanut fields.

Background

In the whole growth period of peanuts, branches and leaves are numerous and dense, the control of diseases and pests is quite difficult, particularly, in the drought period, red spiders are fast in propagation and serious in harm, so that leaves fall off, plants die, and the yield can be seriously reduced, and the peanuts are generally difficult to radically control 2-3 times in chemical control, so that the labor and medicine cost is greatly increased. In order to achieve the best prevention and control effect, save labor, time and cost, a set of very favorable prevention and control technology is summarized in the ordinary work.

Red spiders are generally used in a drought period, and are generally controlled by pyridaben in peanuts, wherein 4 packages of pyridaben are used per mu of land. The effect is still not good after 3 times, and 0.25 worker/mu/time is used.

And the pesticide is used, so that the pesticide residue in the peanuts is not in accordance with the development trend of advocating green foods at present.

Disclosure of Invention

The invention aims to provide an agricultural prevention and control method for red spiders in peanut fields, which overcomes the defects in the prior art. In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:

an agricultural control method for red spiders in peanut fields adopts a water pump to wash plants;

the washing direction is as follows: washing the plant from the root of the plant to the upper direction;

the time of the scouring is as follows: the number of red spiders was observed visually at 25-30 heads/strain.

Further limiting, the flushing is stopped until the inclination of the plant does not return to the right, and the duration is 5-10 seconds.

Compared with the prior art, drought serves as a condition for red spiders to break out, the red spiders existing on the plants can be washed away in a plant washing mode, meanwhile, drought resisting operation can be performed, and operation cost is effectively reduced in a drought resisting and insect killing combined mode;

in addition, the method is also suitable for red spider control of cotton seedlings, soybean seedlings or other plants planted in dry land.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
