Cinnyl Acetate: Low Effective Control of Verticillium Wilt

Verticillium wilt is a common disease that seriously damages cash crops. In addition to tomatoes and cotton, it also infects eggplants, green peppers, and white melons. Muskmelon, straw poem, okra, cabbage, radish, butterbur, earth angelica, thorny bud, soybean, chrysanthemum, rose, etc., the host is very extensive.

The cultivation of crops in the open field began about one month after the planting, with symptoms appearing on the ground and continued until the end of the harvest. Initially, the lower leaves partially wilted and the leaves curled up. After 2-3 days, the disease department changed from yellow to white. The edges of the leaves are more discolored and they are wedge-shaped with the small leaf veins as the center. Next, the discolored part gradually expands, the whole leaflet yellows, and it slowly browns and dies. When the disease is aggravated, the upper leaves also die off in turn and cause chronic wilting of the lower leaves. As a result, plant height decreased, fruit set and growth of fruit were significantly affected. The eradication of Verticillium wilt is involved in the disinfection of bed soil. Prevention and control has always been a difficult problem for growers.

A recent study by Japanese agriculture and forestry experts found that adding cinnamyl acetate and n-butanol to insecticides can be very effective in controlling Verticillium dahliae, and that it is water-based, environmentally friendly, and biologically harmonious; Ester itself is a kind of spice, it does not produce phytotoxicity to the fruit of the crop. It has low toxicity to mammals, narrow spectrum of prevention, and even obvious selectivity. It is safer for non-target organisms. After repeated experiments by experts, it was found that only adding 40 μg/mL can maximize the efficacy of the drug, and the overall cost of using the drug is much lower than that of currently used drugs.

The cinnamyl acetate is a colorless to pale yellow transparent liquid. It is a sweet balsam and rose and vetiver mixed aroma. It is completely harmless to the human body.
