Abstract
Disclosed is a powdery pesticidal composition which comprises a mixture of a coated pesticide comprising a powdery pesticide coated with a thermosetting resin and having a volume median diameter of 10 to 150 μm and a calcium carbonate micropowder having a bulk density of 0.6 g/ml or less, wherein the weight-based ratio of the coated pesticide to the calcium carbonate micropowder is 100:1 to 100:30. The powdery pesticidal composition has good fluidability.
Claims4
A powdery pesticidal composition comprising a mixture of a coated pesticide having a volume median diameter of 10 to 150 μm in which a powdery agrichemical is coated with a themosetting resin, and a calcium carbonate micropowder having a bulk density of 0.6 g/ml or less, wherein the weight ratio of the coated pesticide to the calcium carbonate micropowder is in the range of 100:1 to 100:30.
A method for improving flowability of a powdery coated pesticide which comprises adding a calcium carbonate micropowder having a bulk density of 0.6 g/ml or less to a powdery coated pesticide in which a powdery pesticide is coated with a thermosetting resin, in such an amount that the weight ratio of the powdery coated pesticide and the calcium carbonate micropowder is in the range of 100:1 to 100:30.
