Abstract: A jinggangmycin and ipconazole fungicidal composition, a weight ratio of jinggangmycin to ipconazole being (1-68):(40-1). The fungicidal composition of the present invention has a remarkable synergistic effect in preventing and controlling fusarium head blight of wheat and barley, powdery mildew of wheat and barley, rust of wheat and barley, sheath blight of wheat and barley, leaf blight of wheat and barley, rice blast, rice false smut and rice sheath blight, particularly the synergistic effect in preventing and controlling fusarium head blight of wheat and barley is more remarkable, and the contamination level of DON toxin in grains can be significantly decreased.

Abstract: The invention provides a ?-tubulin segment of a ?-tubulin gene, and also provides an application of the segment in controlling plant diseases and/or enhancing plant disease resistance, inhibiting pathogenic fungal development and pathogenicity, and improving the drug sensitivity of pathogens to tubulin binding agents. The invention also provides an in-vitro interference preparation including ?TubdsRNA segments of the above-mentioned ?-tubulin gene, and an application of the in-vitro interference preparation in breeding a transgenic plant resistant variety. The RNA interference technology of the ?-tubulin gene of the present invention has green and safe advantages of increasing the drug sensitivity of pathogenic fungi, reducing the level of drug resistance, interfering with pathogenicity, enhancing plant disease resistance, controlling a variety of plant diseases, improving the drug sensitivity to a chemical agent (carbendazim), and prolonging the dsRNAs drug retention period by the carbendazim.

Abstract: A pesticide composition for controlling Fusarium head blight, which contains 1 to 150 parts by weight of jinggangmycin and 1 to 30 parts by weight of tebuconazole. The pesticide composition of the present invention has an obvious synergistic effect when used for controlling Fusarium head blight, can remarkably enhance the effect of controlling Fusarium head blight, and increase the ability of the human being in controlling Fusarium head blight of grain crops.
