To obtain an aqueous suspended sulfur composition which has marked controlling effects on plant disease damage and insect pests and which, since it gives a spray liquid prevented from the precipitation of sulfur particles, prevents the formation of a deposit layer (a caking layer) containing sulfur particles hardly redispersible; and to provide a method for controlling plant disease damage and insect pests using the composition.
The aqueous suspended sulfur composition contains sulfur, starch, a surfactant, and water in a compounding ratio of sulfur to starch of 1:0.1-1:5 and which, when dispersed in water in an amount (by weight) of 100 times that of the composition, gives a dispersion with a pH of 4.0-10.0. The method for controlling plant disease damage and insect pests uses this composition.
