The influence of succinic acid 2, 2-dimethyl hydrazide (alar-85) on tomato (lycopersicon escdlentdm mill)
1972
Norman, J.C., Department of Horticulture, University of Science and Technology, Kumasi, Ghana
Both pot and field experiments were conducted to determine the effect of succinic acid 2, 2-dimethyl hydrazide (Alar-85) on the performance of the 'Improved Zuarungu' tomato. Alar was applied at the rates of 1000 and 2000 ppm. Alar retarded plant growth in the early stages. Its effect, however, diminished about 4 weeks after application, and it did not show any effect at harvest. Alar-treated plants exhibited a high degree of resistance to drought. Alar had no effect on flowering but it delayed fruit set and date of first harvest. Alar also did not significantly affect the total yield of the crop. Harvesting peak for Alar-treated plants was concentrated within a 20-day period. Fruit size and quality were improved and the treated plants also produced much firmer fruits with a longer shelf life than control plants.

For several decades growers of pears and apples in California have controlled the codling moth by coating the fruit with chemical insecticides from petal fall through harvest. This preventive approach was necessary because growers lacked effective methods for determining codling moth activity and abundance in their orchards. While this approach has provided effective control, repeated applications of heavy dosages of broad-spectrum, persistent chemical insecticides have been expensive and disruptive to the environment. Beneficial organisms are destroyed which help regulate the abundance of other pests such as spider mites, aphids, and pear psylla. Released from their natural enemies, these pests frequently reach damaging levels, requiring additional pesticide treatments for their control.
