Pollution-free herbicide

Abstract

The invention discloses a non-polluting herbicide, which is characterized in that the composition is calculated in parts by weight: 10-17 parts of polyvinyl alcohol, 10-12 parts of acetone, 1-5 parts of quicklime, and 13-20 parts of nitrobenzene , 15-25 parts of isoproturon, 17-20 parts of wetting agent, 7-10 parts of dimethyl-p-phenylenediamine, 20-30 parts of water. The advantages of this product are: strong action, rapid weeding, no residue, easy to volatilize, can be used repeatedly without causing damage to crops.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular to a pollution-free herbicide. Background technique [0002] In crop production, various weeds are the biggest crop killers except insect pests, so weeding is an important agricultural project. The common weed control techniques are mainly based on contact type or systemic conduction type. Both are through the contact and absorption of plant stems and leaves, so as to enter the plant body to destroy its photosynthesis and the transmission of nutrients in the plant body, thus causing it to wither and die. However, common weeding products such as "Quaimiling" and "Dabaicao", which are common varieties on the market, often cause the surrounding seedlings to be eroded and damaged during the weeding process. In addition, some herbicides specially enhance the slow-release effect in order to kill weeds and prevent the second recurrence of weeds, causing the cell bodies of ...

Problems solved by technology

However, common weeding products such as "Quaimielin" and "Dabaicao", which are common varieties on the market, often cause the surrounding seedlings to be eroded and damaged during the weeding process.

In addition, some herbicides specially enhance the slow-release effect in order to cut weeds and roots and prevent the second recurrence of weeds, causing the cell bodies of normal crops to be damaged in the same way, thus accidentally injuring farmland and crops.
