Abstract
The invention belongs to the technical field of pesticide, and discloses a dithianon water-dispersible granule. The granule comprises the following components in percentage by mass: 20 to 80 percent of dithianon, 3 to 12 percent of wetting agent, 3 to 12 percent of dispersant, 2 to 10 percent of disintegrant, 0.1 to 5 percent of binder and 5 to 72 percent of filler. The components are mixed pro rata, stirred well and then ground so as to give mother powder; the mother powder is well mixed with the binder; and then the mixture is granulated, dried and sieved so as to prepare the dithianon water-dispersible granule. The granule has the advantages of overcoming the disadvantages of suspending agents and wettable powder and reducing pollution on environment, and is mainly used for controlling fruit-tree scab, leaf spot, alternaria leaf spot, vegetable anthracnose and downy mildew.
Description
Technical field:
The invention belongs to technical field of pesticide, be specifically related to a kind of dithianon water-dispersion granule and be used to prevent and treat black spot of fruit tree, leaf spot, spot defoliation, vegetables anthracnose, downy mildew.
Background technology:
Dithianon (dithianon) is the bactericide of BASF European Co.,Ltd's exploitation, and pure product are dark-brown crystalloid solid.Molecular formula is C
14H
4N
2O
2S
2, chemical name is: 2, and 3-dinitrile-1, the 4-anthraquinone dithio, structural formula is:
Dithianon has multiaction mechanism, and to suppress a series of fungies mould by breathing with sulfur-containing group reaction and interference cell, causes disease death at last, when tool is well protected activity, certain therapeutic activity arranged also.Be used to prevent and treat all fruit diseases such as scab, mildew disease, leaf spot, rust, anthracnose, downy mildew, brown rot.
At present, product forms on the dithianon market is wetting powder, suspending agent, the registration crop is pepper anthracnose and Chinese cabbage downy mildew, because wetting powder dust pollution in processing and use is serious, environment and health there are very big harm, and shortcomings such as effective rate of utilization is low, lasting period weak point; Though suspending agent belongs to the environmental protection preparation, but its bin stability is important performance indications, it concerns the performance and the effect of product, and the factor of influence stability is more, require all higher to former concentration, auxiliary agent, pH value, and suspending agent placed and occurred layering or deposited phenomenon for a long time easily, and then influenced the performance of drug effect.Water dispersible granules has had the advantage of wetting powder and suspending agent concurrently, has overcome its shortcoming, is one of emphasis formulation of pesticidal preparations formulation development.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the environmental pollution that exists in the prior art, to be detrimental to health and the problem of properties of product stability and a kind of environment-friendly type, the availability height developed dithianon water-dispersion granule easy to use.Water dispersible granules is to grow up on the basis of wetting powder and suspending agent, and this formulation has effectively overcome the shortcoming of suspending agent and wetting powder, has 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 dithianon water-dispersion granule, it is characterized in that: its composition contains following percentage by weight: dithianon 20%～80%, wetting agent 3%～12%, dispersant 3%～12%, disintegrant 2%～10%, binding agent 0.1%～5%, filler 5%～72%.
Described dispersant is selected from one or more in polycarboxylate, lignosulfonates, alkylphenol polyoxyethylene formaldehyde condensation products sulphate, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, alkylphenol polyoxyethylene, aliphatic amine polyoxyethylene ether, polyoxyethylene carboxylate, the fatty acid glyceride APEO.

Respectively at July 7, July 23, August 5, August 19 respectively spraying medicine once, spray medicine altogether 4 times.Carry out the investigation of state of an illness radix before the dispenser, August 30, autumn growth carried out the preventive effect investigation after stopping to take out life, investigated altogether twice.
Two strains of every sub-district are all investigated, every strain divide East, West, South, North, in five directions investigation young sprouts take out whole blades of giving birth to 5 vigorous current-year branches, write down 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%;
