Appearance: This is an important indicator of pesticide products, which directly reflects the external state of the product. Different pesticide formulations have different appearance requirements. Such as emulsifiable concentrate: stable homogeneous liquid, no visible suspended matter and sedimentation; wettable powder: free-flowing loose powder, should not have agglomerate; suspending agent: a uniform suspension of flow, long-term storage may have a small amount of precipitation or centrifugation Layer, but should be able to return to its original state by shaking at room temperature, and there should be no agglomeration.
Active ingredient content: A specific component of a pesticide product that is biologically active, that is, a component that is effective when a pesticide is applied. The content of active ingredients is the most important indicator in the standards of pesticide products. The content of active ingredients does not meet the standard requirements, which will lead to poor results after application.
Suspension rate: refers to the ability of the active ingredient to remain suspended in the suspension for a certain period of time and to be uniformly dispersed. When the product with good suspension is used in water, all the active ingredients can be uniformly suspended in the water, and the active ingredients can be uniformly sprayed on the crop to be controlled when applied.
