Pesticides (PPP): Pesticides
The quality control tests that are mandatory for each sector ensure the performance of the product and compliance with the legal regulations from the manufacturer's point of view. This also applies to pesticide formulations, which are referred to as Plant Protection Agents (PPP) and must be evaluated for good laboratory practice as part of the OECD declaration of conformity. Pesticide formulations are actually commercial product forms of active ingredients used in agriculture and are applicable, safe and effective.
What are the main areas of application of pesticide formulations?
- Field crops: For products that are grown on large areas, such as wheat, corn, cotton and sugar beets, they are used to control weeds (herbicides), pests (insecticides) and diseases (fungicides).
- Horticulture and fruit growing: They are used for products such as wine, olives, apples, citrus fruits, tomatoes and peppers against pests and fungal diseases.
- Greenhouse cultivation: For vegetables and ornamental plants grown in a controlled environment, they are used in lower doses and with sensitive formulations.
- Forest and ornamental plants: It is used against forest pests, aphids and fungal diseases in ornamental plants.
- Stored products: Pesticide formulations (fumigants, powders) are used in granaries, silos and storage against insect infestation and mold formation.
- Public health area: Special formulations (e.g. aerosols, fumigants) have been developed against pests that endanger human health, such as mosquitoes, cockroaches and fleas.
- Veterinary medicine and animal husbandry: There are pesticide formulations that can be used in stables and sheepfolds against flies, ticks and parasites.
- Water resources and rice fields: Certain formulations are used to combat mosquito larvae or water weeds.
Quality control tests for pesticide formulations
The tests carried out in pesticides (PPP) can be divided into physico-chemical tests, chemical purity and content analyses, stability tests, physical durability tests and biological efficacy tests. With these tests, you as a manufacturer can reconcile your product with the regulations.
OECD CIPAC MT 184 – Suspension Concentrate Suspensibility
The CIPAC MT 184 suspendability test, which is one of the physico-chemical tests,
One of the quality control tests for pesticide formulations and measures what percentage of the aqueous suspension concentrates (SC) remain suspended after a certain period of time when shaking or mixing in water again.
The aim of the test is to test the homogeneous distribution of the active ingredient in the formulation without precipitate, to examine the resizedability in the event of a precipitation and to ensure that the product when used in the field has an even dosage and effectiveness guaranteed.
Let's look at the results from the perspective of the evaluation:
If the level of suspension is above the limit specified in the CIPAC or FAO/WHO specifications (e.g. ≥ 70-90%), the product is considered suitable.
A low suspension ability means that the product does not spread homogeneously during use and decreases its effectiveness.
