  • Isothiazolecarboxylic acid derivatives, rice blast control agents containing the same as active ingredients, and rice blast control method applying the control agents
    Patent number: 5240951
    Abstract: Application of a rice blast control agent containing an isothiazolecarboxylic acid derivative of the below-described formula, which shows excellent activity against rice blast (Pyricularia oryzae) in rice cultivation, to the water surface of a paddy rice field results in the absorption of the derivative through roots of rice plants, so that the resistance of the rice plants can be enhanced. ##STR1## wherein R.sup.1 and R.sup.2 independently mean a hydrogen or halogen atom or a particular group, and Y stands for an OR.sub.3 group (R.sup.3 being a hydrogen or alkali metal atom or a particular group), an NHR.sup.4 group (R.sup.4 being a hydrogen atom or a particular group), or a morpholino group.
    Type: Grant
