Antibacterial composition, pesticide bactericide and crop disease control method

Abstract

The invention relates to the technical field of pesticides, in particular to an antibacterial composition, a pesticide bactericide and a crop disease control method. Active ingredients of the antibacterial composition consist of metconazole, amino-oligosaccharin and tiadinil. The antibacterial composition has good antibacterial and bactericidal effects, is wide in prevention and treatment spectrum, particularly has a good prevention and treatment effect on southern blight and other crop diseases, is low in side effect, and does not influence the seedling emergence rate of seeds, the leaf color and shape of plants and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bacteriostatic composition, a pesticide fungicide and a method for preventing and controlling crop diseases. Background technique [0002] Sclerotinia is also known as sclerotinia root rot and sclerotia seedling blight, and its pathogen is Sclerotium rolfsii. Harmful to the rhizomes of seedlings and young trees. The disease can harm a variety of plants and usually occurs on the rhizomes or stem bases of seedlings. The cortex of the infected rhizome gradually turns brown and necrotic, and the cortex is severely rotted. After the seedlings are damaged, the absorption of water and nutrients will be affected, resulting in poor growth, the leaves above the ground will become smaller and yellow, the internodes of the branches will be shortened, and the branches and leaves will wither in severe cases. When the disease spots surround the stems, the whole plant will die after a wee...

Problems solved by technology

[0003] In the prior art, in the process of disease prevention and control of crops, chemicals such as chemical reagents and biological reagents are inevitably used, or other physical control methods are used, but the general physical control methods are too cumbersome, time-consuming and labor-intensive, and the control effect is poor. Therefore, most of the control methods still use medicaments, but whether it is chemical medicaments or biological medicaments, the control effect of a single medicament is poor, and after a long-term use of a single medicament, it will cause adverse effects on the recycling of soil or the growth of plants, and then Affect the use of drugs

Therefore, in the prior art, different medicaments are combined to prevent and control diseases, but the effect of the combination of different medicaments is uncertain, and it may produce synergistic effects or antagonistic effects.

And the combination of different agents has uncertain effects on different diseases. In particular, there is no compound agent for canker sores in the prior art.
