to reduce rind stain and retard rind ageing in navel oranges;

to counteract the effects of cherry yellows virus diseases in sour cherries;

to produce uniform seedling growth in rice; to promote elongation of winter celery crop;

to induce uniform bolting and increase seed production in lettuce for seed;

to break dormancy and stimulate sprouting in seed potatoes;

to extend the picking season by hastening maturity in artichokes;

to increase the yield in forced rhubarb;

to increase the malting quality of barley;

to produce brighter-coloured, firmer fruit, and

to increase the size of sweet cherries;

to increase yields and aid harvesting of hops;

to reduce internal browning and increase yields of Italian prunes;

to increase fruit set and yields of tangelos and tangerines;

to improve fruit setting in blueberries;

to advance flowering and increase the yield of strawberries; and

also a variety of applications on ornamentals.
