Liquid formulations are generally mixed with water, but in some instances labels may permit the use of crop oil, diesel fuel, kerosene, or some other light oil as a carrier. This section will present more detailed information about the common liquid pesticide formulations.
A pesticide formulation is a combination of active and inert ingredients that forms an most liquid formulations are diluted with water to make a finished spray.
Instead they form a suspension and require constant agitation to prevent settling.
An active ingredient is dissolved in an oil solvent (or liquid carbon dioxide) and propellant. The insecticide is applied as a gas-propelled spray through a fine.
Fao and who specifications for pesticides: a training manual low temperature storage stability • storage test at 0 ºc required for liquid formulations, which may grow crystals, aggregate particles or develop separate phases. Cs formulations may require freeze-thaw test to show that capsules are not weakened by freezing.
Ec - (emulsifiable concentrate) a liquid, homogeneous formulation to be applied after dilution with water.
It is a formulation that combines an active substance dissolved in a water-immiscible solvent with emulsifiers. Oily liquid active ingredients are formulated as ecs based on a nonpolar hydrocarbon solvent (xylene, naphtha, kerosene, c 9 –c 10 solvents).
The abbreviation cipac stands for collaborative international pesticides analytical council. We are an international, non-profit-oriented and non-governmental organization (see contact) devoted to promote the international agreement on methods for the analysis of pesticides and physico-chemical test methods for formulations and to promote interlaboratory programs for the evaluation of test.
Which is the pesticide formulation process by which solid particles are dispersed in a liquid.
Liquid formulations are usually packaged in a bottle to be measured and added to water as suspendible or emulsifiable concentrates.
Most liquid formulations are diluted with water to make a finished spray. However, some labels direct users to mix the product with another solvent such as crop oil or other light oil as a carrier. The three main types of liquid formulations are solutions, suspensions, and emulsions: a solution is made by dissolving a substance in a liquid.
Wide variation in bulk density among solid pesticide formulations. For instance, a pint of almost any insecticide wettable powder will weigh much less than a pint of fungicide that has a high metal content. Greater accuracy can be obtained if one first determines the weight of a given volume of the solid material and then calculates.

Most people who routinely use pesticides are familiar with the term active ingredient. The active ingredient is the component of a pesticide formulation responsible for its toxicity (phytotoxicity for herbicides) or ability to control the target pest.
