Description

Technical Field

[0001] The present invention relates to a wettable powder of agricultural chemicals in granular form.

Background Art

[0002] A wettable powder of agricultural chemicals in granular form needs to disintegrate and disperse quickly after being put into water. As an example of a wettable powder of agricultural chemicals in granular form, a wettable powder of agricultural chemicals containing an active ingredient of agricultural chemicals and a surfactant such as sodium ligninsulfonate is known (Patent Documents 1 and 2).
