Cultivation of rice with simultaneous control of weeds and fungus disease

摘要

It is disclosed that the known treatment of rice in cultivation with propanil to kill weeds without harming the growing rice plant can be modified so as to simultaneously eliminate the incidence of rice blast disease (which usually appears at the same time as weed infestation) by simultaneous treatment of the rice in cultivation with a combination of pentachloronitrobenzene and propanil, both applied from aqueous spray based on an emulsifiable concentrate of the material or materials.
