Chitosan Oligosaccharide Biostimulant is a concentrated liquid formulation combining chitosan oligosaccharide with organic acids, amino acids, humic substances, macronutrients and selected micronutrients. It is intended for both root-zone and foliar application, providing nutritional and physiological support throughout crop development. The formulation is particularly suitable for growers looking to strengthen root activity, improve nutrient utilization and maintain crop performance under environmental stress.
Product Introduction
Shandong Zhongnong Fuyuan Ecological Agriculture Development Co., Ltd. is one of the leading manufacturers and suppliers of fungus gnat natural pesticide in China, also supports high quality customized service. If you're going to wholesale bulk advanced fungus gnat natural pesticide made in China, welcome to get quotation from our factory.
Fungus gnat larvae live around the soil and root zone, where they can damage underground plant tissues and are often difficult to reach with conventional foliar spraying. Chinese chives are particularly vulnerable because repeated harvesting and continuous cultivation create favorable conditions for recurring larval populations.
This product was developed with technical input from microbial specialists from the Chinese Academy of Agricultural Sciences and China Agricultural University. Its multi-component formulation combines active microorganisms with microbial metabolites and plant-derived ingredients.
Unlike a conventional contact spray applied mainly to foliage, Fungus Gnat Natural Pesticide is directed toward the crop base and soil surface so that the treatment reaches the area where larvae are active.

Main Benefits
Biological Management of Fungus Gnat Larvae
The product is formulated for soil-dwelling larvae associated with Chinese chive production. Application focuses on the root zone and bed surface, where pest activity is concentrated.
This targeted method makes the product suitable for farms dealing with recurring Chinese chive maggot or similar fungus gnat problems.
Multi-Component Microbial Formula
The formulation is not based on a single ingredient. It combines viable beneficial microorganisms, microbial metabolites and botanical extracts.
These components work together as part of a biological pest-management approach and provide an alternative option for growers seeking to reduce repeated chemical treatment.
Designed for Root-Zone Application
Fungus gnat larvae are usually hidden below or close to the soil surface. For this reason, correct application placement is especially important.
The diluted solution should be applied thoroughly around the base of the crop and across the bed surface rather than only spraying the upper leaves.
Supports Lower-Pesticide Production
One of the original purposes of the formulation is to address the heavy reliance on chemical pesticides in Chinese chive production.
By incorporating a microbial biological control product into the growing program, growers can reduce unnecessary chemical pesticide use and support production systems focused on lower pesticide residues.

Especially Effective Against Maggot Pests in Chives
Developed for Chinese Chive Maggot Management
Chinese chive maggot is the larval stage of a fungus gnat and can remain hidden around roots and underground stems. Because the pest is protected by the soil, repeated surface pesticide treatments may not always provide satisfactory management.
Fungus Gnat Natural Pesticide takes a different approach by applying the microbial formulation directly to the root-zone environment.
For commercial growers, timing is also important. Application can be made around harvest, preferably after irrigation once excess water has moved into the soil. This allows the diluted product to be sprayed evenly onto the crop base and bed surface.
Where pest pressure is relatively normal, one thorough application may be sufficient according to the original product program. In heavily affected fields, a second treatment can be carried out approximately ten days later.
