Introduction

Microbial pesticides are a type of biological pesticide, including those derived from bacteria, fungi, viruses, and protozoa, either naturally occurring or artificially mutagenized. Fungal pesticides are preparations made from genetically modified microorganisms through artificial propagation and processing, used to control harmful organisms such as diseases, insects, weeds, and rodents. It is a type of microbial pesticide, whose active ingredient is the live fungal cells of the pathogenic organisms targeting the target organism. The fungal cells mainly exist as spores (such as conidia). Conidia (including spores, budding spores, and dormant spores) and mycelium, etc. Conidia are asexually reproducing cells and are the most common form in fungal pesticides. And it serves as the basic unit of the active ingredient. Fungal pesticide technical material refers to a single or combined form obtained from pure fungal strains through biological fermentation. A high-content live fungal preparation containing biological components associated with the fermentation process and/or small amounts of chemical impurities. GB/T 21459 is proposed to consist of 5 parts. ---GB/T 21459.1 Specifications for Drafting Standards for Technical Extracts of Fungal Pesticides. The purpose is to provide standards for technical extracts of fungal pesticides. Develop guidelines. ---GB/T 21459.2 Specifications for Drafting Standards for Fungal Pesticide Powders. The purpose is to provide standards for fungal pesticide powder products. Develop guidelines. ---GB/T 21459.3 Specifications for Drafting Product Standards for Wettable Powder Fungal Pesticides. The purpose is to provide guidelines for the drafting of product standards for wettable powder fungal pesticides. Specifications for drafting product standards for reagents. ---GB/T 21459.4 Specifications for Drafting Product Standards for Fungal Pesticide Oil Suspension Concentrates. The purpose is to provide standards for fungal pesticide oil suspension concentrates. Standards for writing product specifications. ---GB/T 21459.5 Specifications for Drafting Standards for Fungal Pesticide Bait Products. The purpose is to provide standards for fungal pesticide bait products. Develop guidelines. Specifications for Writing Standards for Fungal Pesticide Technical Agents
