Embodiment 9～16

[0044] Embodiment 9~16 water dispersible granules

[0045] The antimicrobial peptide, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain material. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

Abstract

The invention discloses a pesticide composition containing antibacterial peptide and strobilurin bactericide. The pesticide composition comprises an active ingredient A and an active ingredient B. The active ingredient A is an antibacterial peptide. The active ingredient B is selected from strobilurin bactericides such as pyraclostrobin and trifloxystrobin. A weight ratio of the active ingredient A to the active ingredient B is 1: 80 to 80: 1. The pesticide composition produces synergism on a plurality of diseases harmful for agricultural production, reduces a pesticide use amount, reduces pesticide residual quantity on crops, reduces environmental pollution, is safe for the people and animals, has good environment compatibility and reduces disease resistance to the pesticide.

Description

Technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a pesticide composition containing antimicrobial peptides and methoxyacrylate fungicides in crop diseases. Background technique [0002] Antimicrobial peptides are a type of small molecule polypeptides that are widely present in living organisms and have obvious inhibitory and killing functions against pathogenic bacteria, fungi, viruses and even tumor cells. Antimicrobial peptides can be divided into two categories according to their synthesis pathways. The first category is secondary metabolites such as cyclic peptides and pseudopeptides synthesized by the non-ribosomal pathway, which are mainly synthesized by bacteria; the second category is synthesized by the ribosomal pathway. Antimicrobial peptides are not only derived from bacteria but also widely present in animals, plants and microorganisms. Most antimicrobial peptides are linear or cyclic and have bo...
