This invention relates to a method for retarding plant growth by applying to the plant an effective amount of a malonic acid derivative compound. This invention also relates to novel malonic acid derivative compounds and processes for the preparation thereof.

Use of malonic acid derivative compounds for retarding plant growth

This invention relates to synergistic plant growth regulator compositions containing (1) an ethylene response or ethylene-type response inducing agent and (11) a malonic acid derivative compound. This invention also relates to the use of said compositions for inducing synergistic plant growth regulating responses or ethylene responses or ethylene-type responses.

Synergistic plant growth regulator compositions

Herbicidal thiadiazole ureas are provided wherein the 5-position of the thiadiazole ring is hetero substituted and which exhibit enhanced selective herbicidal activity.

Herbicidal thiadiazole ureas

A growth regulation process involving certain phosphonic acid compounds having the general formula: ##STR1## The growth regulation process of the present invention relates mainly, though not entirely, to the inducement of an ethylene response or ethylene-type response in plants and part thereof including, but not limited to, stems, roots, leaves, flowers, buds, and harvested as well as unharvested fruit. The method of the present invention produces a wide variety of plant growth responses including:

Growth regulation methods

Growth regulation process

A method for controlling apical dominance which comprises applying to the plant an effective amount, ranging between about 0.1 lb. and about 16 lbs. per acre of plants being treated, of 2-chloroethylphosphonic acid.

Method for controlling apical dominance

A method for the inhibition of plant growth which comprises applying thereto an effective amount of 2-chloroethylphosphonic acid.

Method for the inhibition of plant growth

The growth of tobacco suckers in tobacco plants is inhibited by applying to the tobacco plants an effective amount of a substituted 2,6-dinitroaniline alone or in combination with a surfactant.

Method for inhibiting the growth of tobacco suckers

A method of protecting plant life from injury due to frost or sub-freezing temperatures which comprises applying to the plant an effective, but non-phytotoxic amount, having regard to the plant being treated of a compound of the formula: ##STR1## wherein R.sub.1 is lower-alkyl;

Method for protecting plant life from injury due to frost or

A method for producing a growth regulating effect in a plant which comprises applying to the plant an effective amount, with respect to the plant being treated, of cinchoninic acid or a derivative thereof.
