Dazomet coated controlled-release granules

Abstract

The invention relates to the field of pesticides preparations and discloses dazomet coated controlled-release granules. The dazomet coated controlled-release granules comprise the following components in percentage by weight: 1-80% of dazomet, 1-70% of a carrier or a binder, 1-20% of a coating material, 1-10% of a film-forming aid, 0.5-5% of an organic solvent. The dazomet coated controlled-release granules are prepared form dazomet serving as an active ingrediment and selected proper film-forming aid, coating material, carrier, binder and the like, have long-lasting and constant prevention effect on nematodes and weeds, is superior to the existing dazomet pesticides, and can be used for effectively protecting crops from pathogenic bacteria, nematodes and weeds.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a danoron-coated controlled-release granule. Background technique [0002] Methron is a low-toxicity broad-spectrum fumigation nematicide, which can also control soil fungi, underground pests and weeds. When applied in wet soil, it decomposes into toxic methyl isothiocyanate, formaldehyde and hydrogen sulfide in the soil, and quickly spreads to the soil particles, effectively killing various nematodes, pathogenic bacteria, underground pests and Germinated weed seeds, thus achieving the effect of cleaning the soil. Cottonon is not only easy to spread in the soil but also has a long duration of effect. It is suitable for controlling various nematodes on vegetables, strawberries, tobacco, fruit trees, and forest trees. [0003] In the agricultural field at the present stage, it is usually made into microparticles or granules, and then applied in furrows or spread, and the rot...

AI Technical Summary

Problems solved by technology

More importantly, after application, the granules or microparticles of Dianlong are greatly affected by soil temperature, humidity and soil structure, and their active ingredients will become lower and lower with time, and the control effect cannot be kept constant for a long time, so they cannot be effective. Long-term protection of crops against pathogens such as nematodes, pests or weeds

If the exposure time is artificially reduced or the dosage is increased in order to prolong the control effect of cotton wool, the content of cotton wool in the soil will be too high, which will cause great phytotoxicity to the crops.

In addition, the granules or granules of dasyron can only be used for soil fumigation before seedlings. If the diseases, insects, and weeds in the soil are not completely eliminated, they cannot be applied again during the growing period of the crops.
