Description
Technical field
The invention belongs to the compounded preparation of pesticide field, be specifically related to a kind of benzene metsulfovax and kresoxim-methyl sterilizing composite.
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.The Oomycete mycosis there is good activity, the benzene metsulfovax also has good bactericidal activity to phytophthora root rot, its sporangial formation and sporangial sprouting there are good inhibitory action under low concentration, but to the release of zoospore and the not effect of movement of zoospore.Similar with the field test results of Cruciferae Pseudoperonospora cubensis to Plasmopara viticola, downy mildew of cucurbits bacterium.The biological chemistry action mechanism of benzene metsulfovax just under study for action, the benzene metsulfovax has the phytophthora infestans of resistance and has the downy mildew of cucurbits of resistance that bactericidal activity is arranged to methoxy acrylic functional group benzamide functional group, infers that the benzene metsulfovax is different from the mechanism of action that contains these functional group's bactericide.And the benzene metsulfovax not affect the oxidation of nucleic acid and protein synthetic, on the not impact of function of phytophthora root rot bacterium protoplasmic membrane.
New type bactericide benzene metsulfovax has very strong prevention, treats, oozes and annotate activity and good lasting effect and resistance of rainwater washing against are arranged.In the 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.
Kresoxim-methyl, English name kresoxim-methyl is as basis, bionical synthetic a kind of brand-new control of plant disease medicament take natural antibiotics stobiluronA.To crop and Environmental security, have high bactericidal activity, be established gradually a kind of new sterilization standard in the whole world.It is very effective to the disease that other bactericide produces resistance.A kind of efficient, wide spectrum, new type bactericide.Kresoxim-methyl not only has the bactericidal activity of wide spectrum, simultaneously with good protection and therapeutic action.With other bactericide commonly used without cross resistance, and longer than the conventional sterilization agent lasting period.Have the selectivity of height, to crop, people and animals and beneficial organism safety, substantially pollution-free to environment.
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 significant 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.

Embodiment
In order to understand better essence of the present invention, be described further by following examples, but the present invention is not limited to these embodiment.In these embodiments, unless otherwise indicated, all percentages are mass percent.
Example of formulations 1: prepare 40% benzene metsulfovax kresoxim-methyl suspending agent.
Take by weighing 10% benzene metsulfovax, 30% kresoxim-methyl, 3% agricultural newborn 600#, 3% agricultural newborn 2201#, 3% lignosulfonates, 0.2% xanthans, 4% ethylene glycol, 0.5% organosilicon, add deionized water and mend to 100%.After the above-mentioned raw materials mixing, emulsification makes 40% benzene metsulfovax kresoxim-methyl suspending agent through high speed shear.
Example of formulations 2:Prepare 24% benzene metsulfovax water dispersion granules agent of Kresoxim.
Take by weighing benzene metsulfovax 6%, kresoxim-methyl 18%, 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 24% benzene metsulfovax water dispersion granules agent of Kresoxim in proportion with above-mentioned prescription.
Biologicall test embodiment 1: the synergy to cucumber downy mildew is measured.
Be mixed to the synergy type of cucumber downy mildew for further understanding benzene metsulfovax and kresoxim-methyl, the inventor is mixed to benzene metsulfovax and kresoxim-methyl and has carried out a large amount of field formulation screening tests, by field trial, we find to reach best control efficiency when benzene metsulfovax, kresoxim-methyl are mixed according to the ratio of 1:3.The use that the two 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 kresoxim-methyl is as follows.
Benzene metsulfovax, kresoxim-methyl are made suspending agent by single dose and test proportion requirement respectively to be tested, 45 g/acres of single dose preparation usage amounts, the mix preparation usage amount is 20 g/acres, unifies dispenser in the cucumber downy mildew their early stage, 7 days, 14 days actual situations of preventing and treating of investigation after the 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 kresoxim-methyl are to the actual field efficacy of cucumber downy mildew.
Result of the test sees Table 1.As can be seen from the test results: after the dispenser 7 days, benzene metsulfovax of the present invention and the kresoxim-methyl composition that is mixed all is better than the preventive effect of single dose to the cucumber downy mildew preventive effect, behind the medicine 14 days, benzene metsulfovax of the present invention and kresoxim-methyl 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, kresoxim-methyl are with the composite formulation of the ratio of 1:3, and the preventive effect after 7 days and 14 days all above other composite ratios, can be brought into play drug effect by this proportioning largely, reaches optimal control efficiency.
Biologicall test embodiment 2: the be mixed field control effectiveness test of composition for preventing and controlling cucumber downy mildew of benzene metsulfovax and kresoxim-methyl.
Reagent agent and dispenser dosage: (1) 40% benzene metsulfovax kresoxim-methyl suspending agent, mu restrains with preparation 20.(2) 24% benzene metsulfovax water dispersion granules agent of Kresoxim, mu restrains with preparation 40.
Contrast medicament and dispenser dosage: (3) 20% benzene metsulfovax wetting powders, mu restrains (4) 20% kresoxim-methyl wetting powders with preparation 45, mu preparation 45 grams.
Spraying time and application method: the dispenser of cucumber downy mildew their early stage is watered even spraying.
The field control effectiveness test result of table 2, control cucumber downy mildew.
Result of the test sees Table 2.As can be seen from the test results: after the dispenser 7 days, benzene metsulfovax of the present invention and kresoxim-methyl be mixed composition to the cucumber downy mildew preventive effect all more than 76%, significantly better than the single dose of contrast; After the dispenser 14 days, benzene metsulfovax of the present invention and kresoxim-methyl be mixed composition to the cucumber downy mildew preventive effect all more than 86%, also significantly better than the single dose of contrast; Each medicament is showed no the poisoning generation in the process of the test, to crop safety.Illustrate that benzene metsulfovax of the present invention and the kresoxim-methyl composition that is mixed is better than single dose, improve actual control efficiency, reduce dosage, reduce cost, reduce medicament to the adverse effect of environment, delay the generation of disease drug resistance, improvement has great significance to agricultural synthesis.
