This invention relates to a new class of organic chemical compounds. More particularly this invention is concerned with derivatives of isophosphinolinone. Compounds of this invention may be employed as active ingredients in herbicides and/or as intermediates in the preparation of other isophosphinolinone derivatives useful to reduce herbicidal injury to treated crop plants.

Isophosphinolinone derivatives

This disclousure relates to regulating the growth of corn plants utilizing substituted-3-phenacylidene-phthalides. More particularly the present disclosure is concerned with a method of treating a corn plant with a substituted-3-phenacylidenephthalide or composition containing such a compound in order to effectively alter the development of the reproductive components of the corn plant.

Use of substituted-3-phenacylidenephthalides as corn plant growth

Certain 3-phenacyl phthalides have been found useful as safening agents to reduce herbicidal injury to rice plants.

3-Phenacyl phthaldide safening agents

Certain 3-phenacylidene phthalides have been found useful as safening agents to reduce herbicidal injury to rice plants.

3-Phenacylidene phthalide safening agents

Certain 3-phenacyl and phenacylidene phthalimidines, and the corresponding naphthoyl derivatives, are novel compounds which possess biological activity in the treatment of plants to control their growth.

3-Phenacyl and phenacylidene phthalimidines and corresponding naphthoyl

Certain novel o-aroylvinyl benzoyl chlorides have been found to possess herbicidal activity against various undesirable plant species.
