Embodiment 1

[0030] Compositions of the invention can be formulated as sustained release granules. For example the following formula:

[0031]

[0032] The preparation method of sustained-release granule of the present invention comprises the following steps:

[0033] A, prepare the original drug and each auxiliary agent according to the above weight percentage, and mix the original drug and the stabilizer evenly to obtain the active ingredient;

[0034] B. Spray the active ingredient onto the inert carrier of the granules and stir evenly, then let it stand for 1-2 hours;

[0035] C. After heating and melting the coating agent, spray it on the surface of the granular inert carrier to wrap it up to obtain the sustained-release granule of the present invention.

[0036] Indoor Activity Evaluation of Compositions

[0037] The medicament used in this embodiment is:

Abstract

The invention discloses a pesticide composition and an application thereof. Active ingredients of the pesticide composition are 1,3- dichloropropene, dimethyl disulfide and dazomet. The composition is suitable for pre-planting soil sterilization of crop fields of vegetables, strawberries, flowers, melons, nursery gardens, orchards, tea gardens, forests, Chinese herbal medicines and the like, can effectively prevent root-knot nematode, soilborne fungal pathogens, soilborne pathogenic bacteria as well as cropland common weeds, especially cyst nematode, fusarium and digitaria sanguinalis in agricultural crop planting. The pesticide composition disclosed by the invention shows unexpected synergism within certain proportion range, and is obviously improved in nematicidal effect, sterilization effect and weeding effect in comparison with a single agent; and meanwhile, using dose, application labor and cost of pesticides are reduced, and harmful effects on environment and pesticide residues are also reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation, and in particular relates to a pesticide composition compounded with 1,3-dichloropropene, dimethyl disulfide and datyron and its application. Background technique [0002] In the past ten years, with the adjustment of agricultural planting structure, protected cultivation has developed rapidly in our country. The national protected area has exceeded 2 million hectares. As an important agricultural measure to increase farmers' income and transform from traditional agriculture to modern agriculture, protected cultivation in China will continue to develop in the future, and the crops cultivated will also change from the current vegetables and strawberries to flowers, melons, and fruit trees. , Nursery, Chinese herbal medicine and other directions. The development of protected areas also provides a suitable environment for the occurrence and development of root-knot nematodes, soil-bo...
