Embodiment 1

[0028] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. The compound emulsifiable concentrate of embodiment 1 osthole and Jinggangmycin

[0029] The compound emulsifiable concentrate of osthole and Jinggangmycin contains osthole 3%, Jinggangmycin 0.5%, emulsifier 0203 12%, Nongru 500# 2%, penetrant OT-99 10%, N, N- Dimethylformamide is 50%, and the balance is made up to 100% with methanol.

[0030] Preparation process:

[0031] Accurately weigh two kinds of active ingredients (osthole and Jinggangmycin) respectively according to the formula, the amount of the active ingredients is calculated in percent, and accurately weigh various auxiliary agents and solvent N,N-dimethylformamide respectively.

[0032] Dissolve Jinggangmycin with N, N-dimethylformamide first, stir until completely dissolved and then add osthole. Stir again until completely dissolved. Then add the emulsifier and stir wel...

Embodiment 2

[0034] The compound emulsifiable concentrate of embodiment 2 osthole and Jinggangmycin

[0035] The preparation process is the same as in Example 1, the difference is that osthole 1.6%, Jinggangmycin 0.4%, emulsifier 0203 10%, agricultural milk 500# 2%, penetrant OT-99 8%, N, N-dimethyl base formamide 40%, and the balance was made up 100% with absolute ethanol.

Embodiment 3

[0036] The compound emulsifiable concentrate of embodiment 3 osthole and Jinggangmycin

[0037] Preparation process is the same as Example 1, and the difference is that osthole 8%, Jinggangmycin 2%, emulsifier 0203 15%, organosilicon penetrating agent (ethoxylated polytrisiloxane) 4%, N, N-dimethylformamide is 50%, and the balance is made up to 100% with methanol.

Abstract

The present invention provides a complex pesticide of osthole and agricultural antibiotic. The effective components include osthole and agricultural antibiotic with the weight proportion of 1 to 6:1 to 8. The agricultural antibiotic is validamycin, kasugamycin or agricultural streptomycin. The complex pesticide of osthole and agricultural antibiotic provided by the present invention has the advantages of obvious additive effect, strong antibacterial activity and relatively small dosage and has obvious effect on prevention and treatment of rice sheath blight, wheat scab or rice blast.

Description

technical field [0001] The present invention relates to a compound of osthole and agricultural antibiotics, in particular to a compound of plant extract osthole and agricultural antibiotics such as jinggangmycin and kasugamycin and its use, belonging to Botanical fungicide pesticide compound. Background technique [0002] Osthole is the main chemical component of Cnidium chinensis, a common Chinese herbal medicine. In medicine, osthole has been used to produce antibacterial, anti-inflammatory, and vaginal trichomonas drugs. And its anti-aging, anti-osteoporosis, anti-allergic and other new biological activities have also been reported. Cnidium extract has been used in agriculture to produce insecticidal and antibacterial pesticides. [0003] Existing data have reported the antibacterial activity of osthole against 9 kinds of phytopathogenic fungi and 6 kinds of phytopathogenic bacteria. Tobacco red spot disease and other pathogenic fungi have good inhibitory effect. Howe...
