Prevent and treat the Paenibacillus polymyxa and the jinggangmeisu composition of rice sheath blight disease
Technical field
The invention belongs to pesticidal preparations, specifically is Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease.
Background technology
Paenibacillus polymyxa is a microbial pesticide, and insecticidal mechanism is prevented and treated the disease effect for mechanism such as broad-spectrum antiseptic material that it produced, site competition and induction of resistance reach; On producing, be mainly used in the control bacterial wilt of ginger at present.Jinggangmeisu is the water soluble antibiotics that is produced by the mutation of streptomyces hygroscopicus well ridge, after the mycelia of Rhizoctonia solani Kuhn touches jinggangmeisu, can be absorbed very soon and in thalline, conduct, disturb and the growth of inhibition somatic cells normal growth, thereby play therapeutic action by thalline; But jinggangmeisu is used to prevent and treat the existing 30 years history of rice sheath blight disease, very easily induces germ to develop immunity to drugs or has produced the antibiotic property of medicine.At present the control Rhizoctonia solani Kuhn is still lacked effective pesticidal preparations.
Summary of the invention
The purpose of this invention is to provide a kind of effectively preventing Rhizoctonia solani Kuhn Paenibacillus polymyxa and jinggangmeisu composition, greatly improved control efficiency, alleviated the pesticide resistance of Rhizoctonia solani Kuhn to jinggangmeisu greatly, result of study shows that Paenibacillus polymyxa and jinggangmeisu have the obvious synergistic effect.
Technical scheme of the present invention is as follows:
Prevent and treat the Paenibacillus polymyxa and the jinggangmeisu composition of rice sheath blight disease, it is characterized in that the composition that mixed by Paenibacillus polymyxa and jinggangmeisu, its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 0.01-100.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease, it is characterized in that the composition that mixed by Paenibacillus polymyxa and jinggangmeisu, its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 0.05-20.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease is characterized in that described its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 0.01-0.1.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease is characterized in that described its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 0.5-1.5.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease is characterized in that described its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 5-10.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease is characterized in that described its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 15-30.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease is characterized in that described its ratio of weight and number is: Paenibacillus polymyxa: jinggangmeisu=1: 50-80.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease, it is characterized in that the described formulations of pesticide are aqua or pulvis, active component content in the composition is: Paenibacillus polymyxa 4000-6000CFU/ μ l, jinggangmeisu weight content 5-12%.
Described Paenibacillus polymyxa and the jinggangmeisu composition of preventing and treating rice sheath blight disease, it is characterized in that the described formulations of pesticide are aqua or pulvis, active component content in the composition is: Paenibacillus polymyxa 6000CFU/ μ l, jinggangmeisu weight content 9.1%.
The present invention presses the Paenibacillus polymyxa of 8000CFU/ μ l, and concentration is 32% jinggangmeisu batching.
Because the mechanism of action of these two kinds of biopesticides is not quite similar, the present invention learns from other's strong points to offset one's weaknesses by the mode of mixed preparing by a certain percentage, be used to prevent and treat rice sheath blight disease, can bring into play the synergy of the two, improved control efficiency, can significantly reduce dosage and can slow down the generation of the germ antibiotic property of medicine again.
