Abstract
The invention belongs to the technical field of pesticides, and discloses an iprodione water dispersible granule. The iprodione water dispersible granule comprises the following components in percentage by mass: 30 to 80 percent of iprodione, 3 to 12 percent of wetting agent, 3 to 12 percent of dispersing agent, 2 to 10 percent of disintegrant, 0.1 to 5 percent of adhesive, and 5 to 62 percent of filler. The components are mixed according to the proportion, are stirred evenly, and then are crushed to obtain mother powder; and the mother powder is mixed evenly with the adhesive and then is granulated, dried, and sieved to obtain the iprodione water dispersible granule. The iprodione water dispersible granule overcomes the disadvantages of suspending agent and wettable powder, reduces the pollution to the environment, and is mainly used for controlling banana freckle, leaf spot disease, apple altermaria leaf spot, and ring rot.
Description
Technical field:
The invention belongs to technical field of pesticide, be specifically related to a kind of iprodione water dispersible granules and be used for control banana freckle, leaf spot, alternaria leaf spot of apple, ring spot.。
Background technology:
Iprodione (iprodione) is the dicarboximide series bactericidal agent of Bayer Cropscience Co.,Ltd's exploitation, and former medicine purity is 96%, registration card number PD20050167, and sterling is the odorless thinless moist crystalloid solid of white or powder.Molecular formula is C
13H
13Cl
2N
3O
3, chemical name is: 3-(3,5-dichlorophenyl)-N-isopropyl-2,4-dioxo imidazoline-1-carboxylic acid amides.
Structural formula is:
Iprodione belongs to broad-spectrum germicide, can prevent and treat the fungi that the benzimidazole systemic fungicide is had resistance.By the Profilin kinases, control the interior signal of cell of many cell functions, comprise that carbohydrate is in conjunction with the interference effect that enters fungal cell's component, therefore, but it is Antifungi spore germination and generation both, also can suppress mycelial growth, namely all influential to pathogen each developmental stage in the history of life, and can play therapeutic action by root absorption.Be mainly used in preventing and treating Botrytis, Monilia, Penicillium, Sclerotinia, Alternaria, long scholar spore genus, Rhizoctonia, Phoma, genus spore belong to, etc. germ various crop, fruit tree and fruit storage phase disease, all have good preventive and therapeutic effect such as the gray mold of the stalk breaks of grape grey mould, tone fruit trees, alternaria leaf spot of apple, Pear black spot, early blight of tomato, strawberry, vegetables etc.
At present, product forms on the iprodione market is wetting powder, missible oil, suspending agent, because wetting powder dust pollution in processing and use procedure is serious, and environmental and human health impacts is had very large harm, and the shortcomings such as effective rate of utilization is low, lasting period weak point; The missible oil product is owing in a large number with an organic solvent, and environmental pollution is larger, and crop is easily produced poisoning; Although suspending agent belongs to the environmental protection preparation, but its bin stability is important performance indications, it concerns performance and the effect of product, and the many factors of impact stability, require all higher to former concentration, auxiliary agent, pH value, and suspending agent placed and layering or deposited phenomenon occurred easily for a long time, and then affected the performance of drug effect.Water dispersible granules has had the advantage of wetting powder, missible oil and suspending agent product concurrently, has overcome its shortcoming, is one of emphasis formulation of pesticidal preparations formulation development.
Summary of the invention
The objective of the invention is in order to overcome the environmental pollution that exists in the prior art, to be detrimental to health and the problem such as properties of product stability and a kind of environment-friendly type, the availability developed are high, iprodione water dispersible granules easy to use.Water dispersible granules is to grow up on the basis of wetting powder and suspending agent, this formulation has effectively overcome the shortcoming of suspending agent, missible oil and wetting powder, having had both the low advantage of environmental protection and use cost, is a main trend of present pesticidal preparations formulation development.
The present invention is achieved by the following technical solutions:
The present invention relates to a kind of iprodione water dispersible granules, it is characterized in that: its composition contains following percentage by weight: iprodione 30%～80%, wetting agent 3%～12%, dispersant 3%～12%, disintegrant 2%～10%, binding agent 0.1%～5%, filler 5%～62%.

Treatment agent is to sigatoka field control effectiveness test result:
Table 2 iprodione water dispersible granules is prevented and treated the sigatoka field trial
Experimental result shows, iprodione water dispersible granules has preferably control efficiency to sigatoka, 10 days preventive effect still reaches 94.44%～95.43% behind the medicine for the third time, can effectively control the generation of sigatoka, preventive effect all is better than according to medicament, in trial stretch, to banana safety, and banana anthracnose, banana freckle there is favorable effect.
Implementation of an application example two: the iprodione water dispersible granules control alternaria leaf spot of apple test of pesticide effectiveness
Test arrangement is in Yi An village, Jia Qu township, Pucheng County, Shaanxi Province, 3 mu of areas, and the age of tree is life in 6 years, seeding row spacing is 2 * 3m.
Treatment agent is provided by Shaanxi Pucheng County Meibang Pesticide Co., Ltd., and the contrast medicament is 50% iprodione wettable powder (commercial), 80% mancozeb wettable powder (commercial).Establish altogether 6 processing, per 4 repetitions, district's group is arranged at random, 3 of every residential quarter apple trees.
Respectively at July 3, July 10, August 17 respectively spraying medicine once, spray altogether medicine 3 times.Carry out the investigation of state of an illness radix before the dispenser, last dispenser dispenser " Invest, Then Investigate " disease index and preventive effect.
Three strains are investigated in every residential quarter, every strain divide East, West, South, North, in whole blades of vigorous 5 current-year branches of five directions investigation young sprout pumping, record total number of sheets, the sick number of sheets, scab number.
Every leaf accounts for leaf area with lesion area percentage is by following standard grading:
0 grade: anosis
1 grade: lesion area accounts for whole leaf area below 5%;
3 grades: lesion area accounts for whole leaf area 6%～15%;
5 grades: lesion area accounts for whole leaf area 16%～25%;
7 grades: lesion area accounts for whole leaf area 26%～50%;
9 grades: lesion area accounts for whole leaf area more than 50%;
