Insecticides are chemical agents used to control pests. Including organic insecticides, plant insecticides, mineral oil insecticides, microbial insecticides. Insecticide is a kind of pesticide with the largest dosage and the largest variety. Generally, most insecticides can only kill insects but not prevent diseases.
Stomach poison. Through the mouth of the insect into its digestive system to play a toxic role, such as trichlorfon.
Pesticides. After contacting with the epidermis or appendage, infiltrate the insect body, or corrode the wax layer of the insect body, or plug the valve and kill pests, such as pyrethroids, mineral oil emulsions.
Fumigant. Use of toxic gas, liquid or solid volatilization and vapor poisoning pests or bacteria, such as methyl bromide, etc.
Internal inhalation of insecticide. It is absorbed by seeds, roots, stems and leaves of plants and transported to the whole plant. In a certain period of time, the original body or its activated metabolites enter the insect body with the pest to feed on plant tissues or suck plant juice, and play a toxic role, such as Dimethoate, etc.
Choosing the right insecticide depends on the target pest's feeding habits and the crop environment. This table summarizes the primary modes of action for professional pest control.
| Mode of Action | Technical Characteristic | Primary Targeted Pests | Typical Active Ingredients |
| Stomach Poison | Toxic effects occur after ingestion and entry into the digestive system. | Chewing pests (Caterpillars, Beetles, Grasshoppers) | Trichlorfon, Chlorantraniliprole |
| Contact Pesticide | Penetrates the insect's epidermis or wax layer upon physical contact. | Sucking pests, Mites, Aphids, Thrips | Pyrethroids, Mineral Oil Emulsions |
| Fumigant | Acts through toxic gas or vapor volatilization in enclosed spaces. | Storage pests, Soil-borne insects, Greenhouse pests | Methyl Bromide, Aluminum Phosphide |
| Systemic (Internal) | Absorbed by roots/leaves and transported throughout the plant tissue. | Sap-sucking insects (Aphids, Leafhoppers, Whiteflies) | Dimethoate, Imidacloprid |

Our team of agronomists and chemical engineers provides comprehensive technical support, helping you select the right mode of action (stomach, contact, or systemic) for your specific crops and pest challenges. We also offer OEM/ODM services and free sample evaluations to ensure our products meet your local market requirements.
Sustainable & Organic Options
We prioritize environmental stewardship by developing advanced microbial and plant-based insecticides. These solutions support Integrated Pest Management (IPM) strategies, reducing environmental impact while effectively protecting yields.
The primary difference lies in the delivery mechanism. Contact insecticides (like Pyrethroids) eliminate pests upon direct physical contact with their outer cuticle, making them ideal for immediate knock-down of visible infestations. Conversely, systemic insecticides (like Dimethoate) are absorbed through the plant's vascular system (roots or leaves). They provide long-term protection from within, effectively targeting sap-sucking insects that are often hidden from surface sprays.
Yes. Suze Chemical is committed to sustainable agriculture. We provide a specialized range of microbial and plant-based insecticides tailored for Integrated Pest Management (IPM) programs. These products are formulated to minimize environmental impact and are suitable for use in sensitive agricultural environments where chemical residues must be strictly managed.
For pests in enclosed environments such as grain silos or greenhouses, Fumigants are the most effective. These agents volatilize into toxic gases that penetrate deep into stored products or soil, reaching pests that traditional liquid sprays cannot access.
