Abstract
The invention relates to a benthiavalicarb isopropyl/chlorothalonil bactericidal composition which is composed of benthiavalicarb isopropyl and chlorothalonil in a mass ratio of 1:1-1:10. The bactericidal composition provided by the invention is suitable for controlling downy mildew of cucumber. The benthiavalicarb isopropyl/chlorothalonil compound has obvious synergistic action, has favorable control effect on downy mildew of cucumber, lowers the pesticide consumption to some extent, saves the cost, reduces the negative influence on the environment, is convenient to use, and has strong operability and high practical application value.
Description
Technical field
The bactericidal composition that the present invention relates to is take benzene metsulfovax and tpn as active ingredient, is used for the control cucumber downy mildew.
Background technology
The benzene metsulfovax, English name: benthiavalicarb-isopropyl, chemical name [[(6-fluoro benzothiazole-2-yl)-ethylamino formoxyl]-2-methyl-propyl] carbamic acid isopropyl ester.New type bactericide benzene metsulfovax has very strong prevention, treats, oozes and annotate active and good lasting effect and resistance of rainwater washing against are arranged.In field trial, the benzene metsulfovax still can effectively be controlled the downy mildew of late blight, grape and other crops of potato and tomato under lower dosage.Benzene metsulfovax and other bactericide are made into mixture, also can extraordinary drug effect be arranged to these germs.
Tpn, English common name: chlorothalonil is wide spectrum, protective fungicide.The mechanism of action be can with the fungal cell in glyceraldehyde 3-phosphate dehydrogenase have an effect, tie mutually entirely with the protein that contains cysteine in this enzyme, thereby destroy this enzymic activity, make fungal cell's metabolism be damaged and lose one's life power.Tpn does not have interior suction conduction, but after being sprayed onto on plant corpus, good tackness can be arranged on body surface, be difficult for being fallen by rain drop erosion, so the drug effect phase is longer.
Cucumber is a kind of at world wide cultivated area vegetable variety widely, cucumber downy mildew is a kind of Common Diseases in the green cucumber process, the harm phase is long, propagation is fast, often cause the significantly underproduction of crop serious period, have a strong impact on quality and economic benefit, develop its relevant control product and have the great market space.

Bactericidal composition of the present invention is mainly used in preventing and treating cucumber downy mildew.
Early stage or the use of disease initial stage of origination should occur in disease in bactericidal composition of the present invention when using.
Bactericidal composition of the present invention adopts the method for spraying to use usually, also can adopt as required upper other operation techniques used of agricultural.
Product described in the invention can finished product preparation form provide, namely in composition, each material mixes, the form that the composition of composition also can single dose provides, and directly mixes in tank or bucket before use, then is diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation, can reach the purpose of control by using suitable formulation.
Bactericidal composition provided by the invention has following characteristics.
1, bactericidal composition provided by the invention, in certain ratio range, cucumber downy mildew is shown obvious synergistic effect, the control efficiency of composition is significantly improved than single dose, can reduce the using dosage of agricultural chemicals, reduce drug cost, reduce agricultural chemicals to the adverse effect of ecotope.
2, two of bactericidal composition provided by the invention kinds of effective ingredient mechanisms of action are different, can overcome the long-term single shortcoming that makes with medicament easily produce resistance, extend the service life of medicament, to the comprehensive regulation important in inhibiting of disease.
3, the bactericidal composition that provides of the present invention is to crop safety.
Embodiment
Below in conjunction with embodiment, content of the present invention is described in further detail, in embodiment, mentioned content is not limitation of the invention, material prescription select to suit measures to local conditions and on result without substantial impact.In these embodiments, unless otherwise indicated, all percentages all are weight percentage.
FORMULATION EXAMPLE 1: 40% benzene metsulfovax tpn suspending agent.
Following material is mass percent: take 8% benzene metsulfovax, 32% tpn, 3% agriculture breast 600#, 3% agriculture breast 2201#, 3% lignosulfonates, 0.2% xanthans, 4% ethylene glycol, 0.5% organosilicon, add deionized water and mend to 100%.After above-mentioned raw materials was mixed, emulsification made 40% benzene metsulfovax tpn suspending agent through high speed shear.
FORMULATION EXAMPLE 2: 60% benzene metsulfovax chlorothalonil water dispersible granule.
Following material is mass percent: benzene metsulfovax 12%, and tpn 48%, sodium lignin sulfonate 4%, naphthalenesulfonic acid-formaldehyde condensate 3%, sodium chloride 2%, soluble starch 1%, polyvinyl alcohol 3%, ammonium sulfate 5%, surplus is kaolin.Dry pulverization process, extruder grain, drying, screening make 60% benzene metsulfovax chlorothalonil water dispersible granule in proportion with above-mentioned formula.
Biologicall test embodiment 1: the combination that is mixed of benzene metsulfovax and tpn is measured the synergy of cucumber downy mildew.
Be mixed to the synergy type of cucumber downy mildew for further understanding benzene metsulfovax and tpn, the inventor is mixed to benzene metsulfovax and tpn and has carried out a large amount of field formulation screening tests, by field trial, we find when benzene metsulfovax and tpn according to～ratio reach best control efficiency when being mixed.The use that both is mixed is significantly improved than the use preventive effect of single formulation, also has great significance than the type control efficiency of other compound proportions.
The be mixed field control effectiveness test scheme of composition for preventing and controlling cucumber downy mildew of the benzene metsulfovax of different quality ratio and tpn is as follows:
Benzene metsulfovax, tpn are made suspending agent by single dose and test proportion requirement respectively to be tested, 30 g/acres of single dose 20% benzene metsulfovax preparation usage amounts, 60% 60 g/acres of tpn preparation usage amounts, the mix preparation usage amount is 80 g/acres, unify dispenser in the cucumber downy mildew their early stage, 7 days, 14 days actual situations of preventing and treating of investigation after dispenser.With this relatively proportioning of different proportion to the actual control efficiency in the field of cucumber downy mildew.
Table 1, benzene metsulfovax, the different proportionings of tpn are to the actual field efficacy of cucumber downy mildew.
Result of the test: see Table 1.As can be seen from the test results, after dispenser 7 days, benzene metsulfovax of the present invention and the tpn composition that is mixed all is better than the preventive effect of single dose to the cucumber downy mildew preventive effect, after medicine 14 days, benzene metsulfovax of the present invention and tpn be mixed composition to the cucumber downy mildew preventive effect all more than 78%, also significantly better than the contrast single dose.Wherein benzene metsulfovax, tpn are with the composite formulation of the ratio of 1:4, and the preventive effect after 7 days and 14 days all over other composite ratios, can be brought into play drug effect by this proportioning largely, reaches optimal control efficiency.
