A method for controlling pests and weeds on or around plants, especially crop plants. The method includes admixing 2-propenal or other related enal compounds to form an aqueous solution, and applying the aqueous solution to plants, plant seeds, weeds, or soil around the around the area in which the plants grow. The aqueous solution contains about 1 to about 1350 parts of the active compound per million parts of water, and is applied to the soil in amounts of from about 75 pounds to about 800 pounds of active compound per acre of soil. At lower application rates of from about 1 pound to about 100 pounds of the active compound per acre of soil, 2-propanol and related enal compounds have the beneficial effect of enhancing the growth of the plants. In addition, application of these enal compounds also helps in reducing transplant shock of tomato plants.
