Problems solved by technology

[0005] As biopesticides, Jinggangmycin and Bacillus velaisi have the advantages of low toxicity, but their disadvantages are also obvious. Jinggangmycin has a short duration of efficacy in controlling cucumber powdery mildew, and Bacillus velaisi has poor efficacy in controlling cucumber powdery mildew. Therefore, the share of chemical pesticides in the medicaments for the prevention and treatment of cucumber powdery mildew is increasing, but chemical pesticides are more toxic than biological pesticides, which affects food safety. Therefore, it is urgent to develop a kind of effective, low toxicity, long-lasting biocides

Embodiment 1

[0016] Example 1 Indoor Toxicity Test of Jinggangmycin Complex against Cucumber Powdery Mildew

[0017] In this example, the cucumber powdery mildew pathogen was collected from the field and purified and cultivated indoors.

[0018] Test method: After pre-testing to determine the effective inhibitory concentration range of each agent, Bacillus velei, Jinggangmycin and their mixed preparations were serially diluted to 5 concentrations according to the gradient of active ingredient content, and sterile water was used as a control. For the determination of silk growth rate, add different concentrations of drugs into sterilized petri dishes, 1mL per dish, then add 9mL of sterilized and melted PDA medium, mix well to make a plate, and then expand the colonies to reach 0.5cm. Cake, one piece per plate, repeated 3 times for each treatment, cultured in a 28°C incubator, measured the diameter of the colony after 4 days of culture, calculated the inhibition rate of mycelial growth, obta...

Embodiment 2

[0025] Example 2 Compound Jinggangmycin and Bacillus Velesi at a weight ratio of 1:2 to carry out a field test on the control of cucumber powdery mildew. According to the requirements in the table, different medicaments were made into corresponding concentrations. Spray once, spray for the second time 7 days later, apply twice altogether, measure disease index 7 days, 14 days, 21 days after spraying, calculate drug effect.

Embodiment 3

[0029] Example 3 Compound Jinggangmycin and Bacillus veleisi at a weight ratio of 3:1 to carry out a field test on the control of cucumber powdery mildew. According to the requirements in the table, different medicaments were made into corresponding concentrations. Spray once, spray for the second time 7 days later, apply twice altogether, measure disease index 7 days, 14 days, 21 days after spraying, calculate drug effect.

Abstract

The invention relates to a validamycin containing fungicidal composition and an application thereof and belongs to the technical field of agricultural control. The fungicidal composition contains active ingredients, i.e., validamycin and Bacillus velezensis, wherein based on that the Bacillus velezensis containing 100 billions of cfu / g is set as a 100% technical concentrate, the weight ratio of the validamycin to the Bacillus velezensis is (15: 1) to (1: 15). The fungicidal composition has the following advantages and remarkable technical effects that the validamycin and the Bacillus velezensis are different in action mechanism, and the synergistic effect of mixing of the validamycin and the Bacillus velezensis is obvious, so that the pesticide efficiency can be greatly increased, and thepesticide consumption and medication cost are reduced. Meanwhile, by the composition disclosed by the invention, the effect duration of the validamycin can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural control, and in particular relates to a bactericidal composition containing Jinggangmycin and its application. Background technique [0002] Cucumber powdery mildew, commonly known as "white hair disease", is one of the common diseases in cucumber cultivation. Because powdery mildew affects the photosynthesis of leaves, it causes a great loss of yield in the late growth period of cucumber. Especially in recent years, a certain amount of drug resistance has been produced, so that the production reduction in general years is about 10%, and the production reduction in popular years can reach about 40%. At present, chemical agents are generally used for the prevention and treatment of cucumber powdery mildew, and there is a risk of pesticide residues. It is urgent to develop a high-efficiency Low toxicity biopesticide. [0003] Jinggangmycin, also known as effective mycin, is an antibiotic produ...
