Embodiment 1

[0028] A control agent for broad-leaved weeds in pepper gardens, the preparation method of which is:

[0029] S1 is composed of Zanthoxylum bungeanum extract and chestnut shell extract mixed in equal mass ratio, then add microcrystalline cellulose solution with a mass fraction of 45% to a solid-liquid ratio of 1:19, and disperse for 40 minutes under ultrasonic conditions with a frequency of 60 kHz to obtain a suspension A standby;

[0030] S2 Add activated urea solution to glyphosate to a solid-to-liquid ratio of 1:12, disperse for 15 minutes under ultrasonic conditions with a frequency of 35 kHz, and obtain suspension B for later use;

[0031] S3 takes half of the suspension A, then pours it into the suspension B, and then pours the remaining suspension A, after boosting the pressure, then drops to normal pressure at a rate of 6MPa / min to obtain the product;

[0032] The preparation method of the Zanthoxylum bungeanum extract is as follows: put the Zanthoxylum bungeanum in a...

Abstract

The invention belongs to the technical field of weeding, and particularly relates to a control agent for broadleaf weeds in a pepper garden. The preparation method comprises the following steps of mixing a Chinese prickly ash extract and a chestnut shell extract, then adding a microcrystalline cellulose solution, and dispersing under an ultrasonic condition to obtain a suspension A for later use;S2, adding an activated urea solution to glyphosate, and dispersing under the ultrasonic condition to obtain a suspension B for later use; and S3, taking half of the suspension A and then pouring intothe suspension B, and then pouring the rest suspension A, carrying out pressurizing treatment and then reducing to the normal pressure to obtain the control agent. The control agent is specially usedfor killing broadleaf weeds and is harmless to pepper; by means of complementation of different action mechanisms, the characteristics of contact killing and internal attraction are achieved, so thatthe adaptability to low temperature, moisture and microorganism adverse environment is increased, the application adaptation period is prolonged, the reaction speed is increased, and the weeding effectiveness is improved.

Description

technical field [0001] The invention belongs to the technical field of weeding, and in particular relates to a control agent for broad-leaved weeds in pepper gardens. Background technique [0002] Pepper is a solanaceous vegetable. During the growth of pepper, the damage of weeds has always been an important factor affecting the high-quality and efficient production of pepper. The planting season of pepper is generally in the rainy season, which is the period of vigorous growth of weeds. Weeds are an important factor in the farmland ecosystem. Biological components are also a key factor restricting agricultural production. It competes with crops for land, light, fertilizer, and water, and induces pests and diseases. It is one of the main factors that affect crop growth and lead to yield reduction. [0003] The broad-leaved weeds that are more harmful in the pepper field include horse pickled melon, retroverted amaranth, velvetleaf, snakehead sausage, purslane, shepherd's pur...
