How to choose insecticide with different formulas？

Insecticide is mainly classified into three categories based on the different carrier solvents: oil-based, water-based and alcohol-based formulations. Understanding the characteristic differences of these formulas is crucial for agricultural production, home pest control and public health fields. Each formula has its unique physicochemical properties, which directly affect the penetration, residual time and effect of the insecticide. Research by the United States 環境保護庁（EPA） shows that choosing the right pesticide formula can increase the insecticidal effect by 30-50%, while reducing the impact on the environment and non-target organisms.

Oil-based insecticides use mineral oil or vegetable oil as the main carrier. Common formulations include emulsifiable concentrate (EC) and ultra-low volume spray (ULV). The most distinctive feature of this type of insecticide is its strong permeability, which can penetrate the waxy epidermis of insects and is particularly effective against pests such as scale insects and aphids that are protected by wax.

According to the experimental data from the Agricultural Research Center of the University of Florida, the fatality rate of oil-based pesticides to certain pests is 40% higher than that of water-based formulas. Its main advantages include: excellent coverage and adhesion; It can penetrate the protective wax layer of insects; The duration of effect is relatively long (usually 7 to 14 days); It is not affected by water hardness.

Drug damage is prone to occur at high temperatures (use with caution when the temperature exceeds 32℃). It may harm the tender leaves and flowers of some plants; It is highly toxic to aquatic organisms. It is easy to leave visible oil stains on the surface of plants.

Control of scale insects on fruit trees such as citrus and apple trees; Greenhouse crops are used in the cool season; Outdoor places that require long-term protection; Environments sensitive to water (such as pest control in areas of electronic devices).

Water-based insecticides, which use water as the main solvent, have seen the fastest growth in market share in recent years, mainly due to their environmental friendliness and safety in use. Its advantages include: high safety for plants and less likely to cause phytotoxicity; It has no irritating smell and is suitable for indoor use. Easy to clean and leave no trace; The toxicity to mammals is generally low.

It is easily washed away by rain (the duration of effect is usually only 3 to 7 days). It has a relatively weak penetrating power against certain pests. The hardness of water quality may affect the effect. It has poor spreadability on hydrophobic surfaces.

Indoor pest control in households (such as cockroaches, ants, etc.) Vegetable crops with tender leaves; Application in farmland during the hot season Places where pesticides need to be applied frequently.

Alcohol-based insecticides use ethanol or isopropyl alcohol as carriers and are commonly found in aerosols and certain specialized insecticidal products. The most prominent feature of this type of formula is its rapid knockdown effect and strong volatility. According to a study published in the Journal of Medical Entomology, alcohol-based formulations knock down flying insects 2 to 3 times faster than oil-based ones. Its main advantages include: rapid effect, showing results within a few minutes; Completely volatilize without leaving residue; Suitable for use around precision instruments; It has a certain disinfection effect.

The duration of effect is extremely short (usually no more than 24 hours); Flammable, with safety hazards during storage and use; It is soluble in certain plastics and coatings; The cost is relatively high.

Emergency situations that require the rapid extermination of flying insects; Sensitive environments such as hospitals and laboratories; Areas with dense electronic equipment It is used as a “space spray” for the immediate control of mosquitoes and flies.

Scale insects and mites: Oil-based formulas are preferred

Flying insects (mosquitoes, flies) : alcohol-based or oil-based space spray

Cockroaches and ants: Water-based residual spray

Soil pests: Oil-based or special water-based formulations

High-temperature weather: Avoid oil-based and choose water-based

Rainy season: Choose oil-based or water-based products with added additives

Indoor enclosed space: water-based or alcohol-based

Near water sources: Oil-based substances are prohibited and specific water-based substances should be selected

By scientifically understanding the characteristics of different formula insecticides and combining them with specific pest species and environmental conditions, we can make the best choice, effectively controlling pests while minimizing the impact on the environment and human health to the greatest extent.
