Abstract

The invention relates to a pesticide composition; it comprises difenoconazole and thiophanate-methyl, and is used in preventing and controlling agricultural disease. It is especially suitable for preventing and controlling melon powdery mildew and wheat powdery mildew.

Description

The composition that contains Difenoconazole and thiophanate-methyl with bactericidal action
Technical field
This invention relates to a kind of composition pesticide, is made up of Difenoconazole and thiophanate-methyl, is used to prevent and treat the disease on the agricultural.Especially be suitable for preventing and treating cucurbits powdery mildew and powdery mildew of wheat and barley.
Technical background
Difenoconazole is a kind of systemic fungicide with protection and therapeutic action, is table angle sterol biosynthesis inhibitor.It has strong interior absorption, drug effect height, to crop safety, and long characteristics of lasting period.Have prevention and therapeutic action.
Thiophanate-methyl is a kind of bactericide of wide spectrum, high-efficiency low-toxicity.The mechanism of action is the formation of imitative hammer body in the mitosis of disturbing bacterium, thereby influences cell division.Have protection and therapeutic action.
In the real process of agricultural production, preventing and treating the problem that disease is easy to generate most is the drug-fast generation of germ.Important powdery mildew on the agricultural often takes place in the melon crop growth later stage because its spread speed is fast, and host range is wide, is easy to generate resistance especially.In some powdery mildews serious place of causing harm, common bactericide such as tpn, carbendazim, use has not had any effect separately.Triazolones etc. have also caused very serious resistance, and have been easy to generate poisoning owing to large-area application.
Go up the powdery mildew that produces resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But, the development cost height of new active ingredient, the construction cycle is long, and all produces the speed of resistance forever less than germ.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.
The composition of different cultivars carries out composite, is to prevent and treat the very common way of resistance germ.Heterogeneity is carried out composite, according to the effect of practical application, judge certain composite be synergy, add and or antagonism.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby delayed the generation of pest resistance to insecticide greatly, and be the important means of integrated control insect.Still nobody reported in the composite and application of Difenoconazole and thiophanate-methyl at present.
Summary of the invention
In order to prevent and treat the disease on the agricultural, we have carried out mutual composite synergy research with compositions such as Difenoconazole, thiophanate-methyls.It is tested object that powdery mildew and wheat powdery mildew on the cucumber are adopted in test, and concrete grammar is:
1) powdery mildew of cucumber.Test medicine provides former medicine for producer, is mixed with the preparation that needs by my research department of company.Take back the powdery mildew of cucumber leaf that adopt back in the field indoor, the cultivation 24h that preserves moisture about 21 ℃ impels and forms more spore on the scab, wash with sterile water then, be diluted under low power lens in (10 * 15) each visual field 3-5 spore and be advisable, and in spore suspension, add 0.25% gelatin to improve the adhesivity of spore on the blade face.
The test method that test adopts blade to preserve moisture and inoculate.Select growing way prosperous after long the to the 3rd to the four true leaf expansion of potted plant cucumber, growth is used (every basin field planting 5 young plants) for connecing the bacterium test uniformly, and every processing repeats 8 times.On pretreated basis series concentration is set, each handles earlier constant spray medicine routinely then, connects bacterium behind the 24h, every basin spray bacterium liquid 5ml, and inoculation back insulation (21-24 ℃) is preserved moisture (relative moisture is greater than 90%) to guarantee the invasion of germ.After morbidity is stable, investigates disease index according to powdery mildew of cucumber grade scale complete stool, and make evaluating drug effect with blank.Ratio is mass ratio.
Statistical analysis technique:
1, state of an illness grade scale:
0 grade: blade does not have scab
1 grade: lesion area accounts for below 5% of whole blade area;
3 grades: lesion area accounts for the 6-10% of whole blade area;
5 grades: lesion area accounts for the 11-25% of whole blade area;
7 grades: lesion area accounts for the 26-50% of whole blade area;
9 grades: lesion area accounts for more than 50% of whole blade area.
2, computational methods:
Figure A20061014712200042
Calculate concentration EC in virulence equation and the inhibition with method of least squares 50, calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC value) according to the abundant method of Sun Yun, CTC value greater than 100 be synergistic effect, equaling 100 is addition, is antagonism less than 100.
2) wheat powdery mildew.Test medicine provides former medicine for producer, is mixed with the preparation that needs by my research department of company.Take back the wheat powdery mildew leaf that adopt back in the field indoor, the cultivation 24h that preserves moisture about 21 ℃ impels and forms more spore on the scab, wash with sterile water then, be diluted under low power lens in (10 * 15) each visual field 3-5 spore and be advisable, and in spore suspension, add 0.25% gelatin to improve the adhesivity of spore on the blade face.
The leaf test method of preserving moisture is adopted in test.It is consistent to get size earlier, the wheat leaf blade that growth is consistent, and each handles 10 leaves, and every processing repeats 8 times.On pretreated basis series concentration is set, each handles earlier constant spray medicine routinely then, connects bacterium behind the 24h, and each handles spray bacterium liquid 5ml, and the insulation (21-24 ℃) in box of inoculation back is preserved moisture (relative moisture is greater than 90%) to guarantee the invasion of germ.After morbidity is stable, investigates disease index according to wheat leaf blade powdery mildew grade scale complete stool, and make evaluating drug effect with blank.Ratio is mass ratio.
Statistical analysis technique:
2, state of an illness grade scale:
0 grade: blade does not have scab
1 grade: lesion area accounts for below 5% of whole blade area;
3 grades: lesion area accounts for the 6-10% of whole blade area;
5 grades: lesion area accounts for the 11-25% of whole blade area;
7 grades: lesion area accounts for the 26-50% of whole blade area;
9 grades: lesion area accounts for more than 50% of whole blade area.
2, computational methods:
