SIMULTANEOUS CONTROL OF SEED AND SEEDING ROT* AND BLAST OF RICE PLANT

摘要

PURPOSE:To control seed and seeding rot, and blast of rice plant efficiently and simultaneously without providing rice plant with phytotoxicity, by scattering kasugamycin or its salt in the form of dust over seeds in a box for growing uoung rice plant after seeding. CONSTITUTION:Kasugamycin or its salt in the form of dust is scattered over a seed layer after seeding in a weight ratio of an active ingredient to one box (30cmX 60cmX3cm) for growing young rice plant of 50-500mg. Seed and seeding rot of rice plant, and blast which has been slightly prevented, can be controlled simultaneously by an extremely small amount of the dust with reduction of labor. The dust includes dust which can be prepared conventionally in the production of agricultural chmemicals, DL dust, and wettable powder.
