The choice of insecticide formulation is usually as important as the choice of the active ingredient in the insecticide. When using liquid sprays, pest management professionals can choose from formulations such as suspensions (SC), wettable powders (WP), capsule suspensions (CS), water dispersible granules (WDG) and emulsifiable oils (EC). Insecticide baits have become an important formulation in pest management programs, and PMPs can choose from a variety of forms of baits, including ready-to-use bait stations, gel baits, granular baits, and liquid baits.


Professionals may also choose to use aerosol, dust or pellet insecticides as part of their management program. When combined with the decision to select the most effective active ingredient, product selection can be overwhelming, even for the most experienced technician. Owners/managers must manage their pesticide inventory to control chemical costs, but at the same time ensure that sufficient formulations are available for a safe and effective management program. The following Integrated Pest Management (IPM)-based process can help in selecting the best formulation for the job.

Before selecting a formulation, it is helpful to know the areas to be treated. A thorough inspection of the property will provide the information needed to select the best formulation for the job. Before proceeding with an insecticide application, carefully consider the following questions regarding formulation selection.


1. Can the formulation be safely applied to a sensitive area?

Sensitive areas may include food areas of food handling facilities, hospital or nursing home rooms, classrooms, certain areas of zoos, and many other locations. Special precautions must be taken in these areas to avoid the potential hazards of pesticide use. First, make sure the product is labeled for use in these areas. Residual sprays may be limited to crack and crevice treatments and may be prohibited when the room is occupied. Choose formulations with low or no odor and products with low vapor pressure. Decoy formulations are often an excellent choice for sensitive areas.


2. Will the formulation cause phytotoxicity (plant damage) to the treated plants?

Phytotoxicity may occur following the application of insecticides to plants. This is more likely to occur when using liquid formulations such as EC formulations that contain solvents. When plants are to be treated, choose formulations that do not contain solvents (e.g., WP, SC, CS formulations).


In addition, do not treat plants in direct sunlight during the hottest part of the day. This combination of environmental factors can cause the leaves of the plant to "burn". Other causes of phytotoxicity may be attributed to the use of excessive rates, treatment of sensitive plant species, cumulative applications to the same plants and product mixtures. Extensive phytotoxicity tests conducted by manufacturers on their products can often provide information on phytotoxicity. If in doubt, try the product on a small sample of plants first.


3. Will the formulation perform well on the surface to be treated?

The interaction of residual insecticide formulations and surface treatments greatly affects the performance of insecticides. Residual insecticides are suitable for a wide range of surface types. These surfaces can be described as porous, semi-porous or non-porous types. Examples of porous surfaces include: concrete, wood cladding, unfinished wood, gypsum wallboard, paper, and plastic. Common non-porous surfaces are glass, tile, and stainless steel. Semi-porous surfaces such as enamel and latex painted wood, vinyl tile and glued wood are also encountered.

Bifenazate + Etoxazole

Bifenazate + etoxazole is a classic formula in acaricides. Bifenazate mainly acts on the central nervous conduction system of mites. The good killing effect is, a long-lasting effect; oxazole mainly inhibits the embryo formation of mite eggs and the molting process from larvae to adult mites and the lasting effect can reach more than 50 days. After the two are mixed, the synergistic effect is obvious.



Abamectin has contact and stomach poisoning effects on mites and can maintain a long residual effect; oxazole can inhibit the embryo formation of mite eggs and the molting process from larvae to adult mites and is effective for eggs and larvae. Therefore, the compound is suitable for the whole growth period of citrus and can kill eggs, young nymphs, and adult mites.

It has a higher toxic effect on a variety of pests, especially mouthpart pests, and a wide range of insecticides. It can control aphids, red spiders, leaf miners, thrips, fruit flies, leaf bees, planthoppers, leafhoppers, etc.



Diflubenzuron is a kind of insecticide of the chlorbenzuron group, which is an insect growth regulator discovered in the 1970s.It has stomach poisoning and contact-killing effects on pests. By inhibiting the synthesis of insect chitin, the larvae cannot form new epidermis during molting, and the insect body becomes deformed and die, It has specific effects on lepidopteran pests.



Dinotefuran has the characteristics of contact killing, stomach toxicity, strong root absorption, high quick-acting, long-lasting period of 4-8 weeks, broad insecticidal spectrum, etc., and it has excellent control effect on mouthpart pests, and is the very low dosage and shows high insecticidal activity.




Numerous studies have shown that EC formulations are absorbed by porous or semi-porous surfaces and that the active ingredient is not available for crawling pests. formulations such as WP, SC, CS and D formulations are not readily absorbed by porous surfaces and are more likely to be "absorbed" by crawling pests. Therefore, if the target pest is a crawling pest, choose a formulation that stays on the surface. However, if the target pest is found below the surface (e.g., wood boring beetles), EC formulations are recommended. During the inspection and prior to application, determine the most common surface types and identify the target pests. Once this information is gathered, you will be able to select the most effective formulation.



One of the biggest challenges professionals face is gaining the cooperation of their clients to maintain good hygiene practices. In the real world of pest management, many treated surfaces are coated with oil, grease, food residue, dirt or other organic materials. Many studies have shown that these surface coatings can reduce the effectiveness of residual pesticides. Professionals can improve pesticide performance by encouraging clients to maintain high levels of sanitation.
