Abstract
The invention discloses a compound pesticide used for controlling paddy rice sheath blight. The invention belongs to the technical field of compound pesticides. The compound pesticide comprises bacillus marinus and jingganmycin, wherein a weight ratio of bacillus marinus to jingganmycin is 1:0.0005-500. According to the invention, because the two biological pesticides are different in action mechanisms, through the compounding of the two, a synergetic effect is developed, pesticide dosage is reduced, controlling effect is improved, controlling time is prolonged, and the occurrences of drug resistance are reduced.
Description
Technical field
The invention belongs to technical field of compounded pesticide, be specifically related to a kind of Recompounded pesticide of preventing and treating rice sheath blight disease.
Background technology
Rice sheath blight disease is a kind of common disease, the frequently-occurring disease of China paddy rice.Common control medicament has jinggangmeisu etc., and jinggangmeisu claims again valida, belongs to low toxicity bactericide.Jinggangmeisu has stronger interior absorption, easily by mycelia, is absorbed and conduction rapidly in its body, suppresses mycelial growth and grows.Be mainly used in rice sheath blight disease, also can be used for the control of the crop pests such as rice green smut and vegetables and cotton, shortcoming is that the lasting period is short, and generally at 7～15 days, along with the long-term use of jinggangmeisu, preventive effect declines to some extent.
Bacillus marinus B-9987, belongs to the class biocontrol bacteria of bacillus, and wild strain is well-grown in sea water medium or in the synthetic medium (preparing with fresh water) of high saliferous.By bio-reactor National Key Laboratory of East China University of Science, from intertidal zone, Bohai Sea halophytes, be separated to, through less salt domestication, obtain with mutation breeding, the outer metabolite of born of the same parents is to Fusarium oxysporum, eggplant interlinkage spore, verticillium dahliae, Rhizoctonia solani Kuhn, the good (agricultural chemicals of the pathogenic fungi preventive effects such as yellow cladosporium, 2008,47(9): 691～693).
Summary of the invention
The problem existing for prior art, the object of the invention is to that design provides that a kind of lasting period is long, control efficiency good, the technical scheme of the quick-acting fast and Recompounded pesticide of preventing and treating rice sheath blight disease that cost is low.

Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that described bacillus marinus and the weight proportion of jinggangmeisu are 1:5～20.
Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that described bacillus marinus and the weight proportion of jinggangmeisu are 1:30～50.
Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that described bacillus marinus and the weight proportion of jinggangmeisu are 1:60～100.
Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that the described formulations of pesticide are aqua or pulvis, and in composition, active component content is: bacillus marinus 500～8000CFU/ul, jinggangmeisu content is 5～12%.
Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that the described formulations of pesticide are aqua or pulvis, and in composition, active component content is: bacillus marinus 1000～5000CFU/ul, jinggangmeisu content is 8～12%.
Described a kind of Recompounded pesticide of preventing and treating rice sheath blight disease, is characterized in that the described formulations of pesticide are aqua or pulvis, and in composition, active component content is: bacillus marinus 6000CFU/ul, jinggangmeisu content is 8%.
The present invention is according to 10000CFU/ug bacillus marinus, the jinggangmeisu batching that concentration is 28%.
Bacillus marinus in the present invention is the active bacteria formulation that the fermentation of bacillus marinus B-9987 produces, and this active bacteria formulation is buied by Shanghai Ze Yuan marine organisms Science and Technology Ltd..
What in the present invention, the preparation of aqua or pulvis adopted is conventional reagent of the prior art.
The present invention is because the mechanism of action of these two kinds of biopesticides is different, composite by the two, can bring into play synergistic effect, reduces dosage, improves preventive effect, extends the control time, reduces pesticide resistance and occurs.
