Claims12
A method of decreasing effects on plants from drought, chilling, flooding or heat stress comprising applying from about 500 ppm to about 2000 ppm of piperonyl butoxide and an effective amount of abscisic acid or salts thereof to the foliage of plants that are susceptible to drought, chilling, flooding or heat stress.
A method of increasing the drought mitigating activity of S-(+)-abscisic acid comprising applying from about 500 ppm to about 2000 ppm of piperonyl butoxide and an effective amount of S-(+)-abscisic acid or salts thereof to the foliage of plants that are susceptible to drought stress.
A method of lengthening the time of the effectiveness of S-(+)-abscisic acid in treating plants comprising applying an effective amount of S-(+)-abscisic acid or its salts to the foliage or potting soil of a plant in need of treatment and from about 500 ppm to about 2000 ppm of piperonyl butoxide to the foliage of said plant.
An agricultural composition for decreasing effects on plants from drought, chilling, flooding, or heat stress;
- comprising and effective amount of S-(+)-abscisic acid or its salts and from about 500 ppm to about 2000 ppm of piperonyl butoxide.
