Abstract
Chemicals containing an effective amount of a polymer of a specified salt of diallylamine derivative and/or a diallyl quarternary ammonium salt exhibit a remarkable effect of preventing agricultural plants from being infected with viral diseases in plants. A method for controlling viral diseases in plants by using an effective amount of such polymer is described.
Claims17
A method for preventing viral diseases in plants comprising applying to said plants an antiviral effective amount of a polymer produced by the polymerization of one or two compounds expressed by the following general formula:
- ##STR28## wherein R.sup.1 and R.sup.2, which may be the same or not, represent a hydrogen atom or an alkyl group having 1-5 carbon atoms which may be substituted by a halogen atom, a hydroxyl group or a cyano group, or together form a pyrrolidine, piperidine, or morpholine ring with the nitrogen to which they are attached, and X is a halogen atom.
A method according to claim 1 comprising applying to said plants an emulsion or solution for controlling viral diseases in plants comprising 10-60 parts by weight of the polymer of claim 1, 20-90 parts by weight of a solvent, and 1-20 parts by weight of a surface active agent.
