Abstract
The invention discloses a fungicide composition adopting metrafenone as a main component. The fungicide composition comprises effective components metrafenone and proquinazid at the mass ratio of (1:100) to (100:1). The composition is obvious in synergistic effect, high in control effect, suitable for prevention and treatment of various diseases on cereals, melons, fruits and vegetables and especially suitable for prevention and treatment of powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition, particularly relating to a kind of take metrafenone as the bactericidal composition of main component and the application of control corps diseases thereof, belongs to technical field of pesticide.
Background technology
Powdery mildew is the plant disease caused by the Erysiphaceae (Erysiphacesae) in fungi.Mostly be ectoparasitism, the whole or large portion of mycelium is exposed to the leaf of host plant, stem, the tender tip, bud, flower and fruit real surface, and produces the macroscopic white powder thing be made up of mycelium, conidiophore and conidium in a large number.
Powdery mildew is widely distributed in the whole world, and dicotyledon of causing harm is particularly general.The main powdery mildew of China has the Cereal powdery mildew caused by standing grain powdery mildew (Ery-siphe graminis); The powdery mildew of the various plants such as melon, the beans caused by Siberian cocklebur monofilament shell (Sphaerotheca fuliginea), crudefiber crop; The wheat powdery mildew caused by wheat snag shell (Uncinula necator); The powdery mildew of more than the 80 kind of trees such as mulberry, pears, persimmon, walnut, chestnut, lichee, papaya papaw caused by hazel ball pin shell (Phyllactinia corylea); The powdery mildew etc. of the Flowers of Rosa caused by rose monofilament shell (Sphaerothecapannosa).
Cucurbits powdery mildew is the important disease in melon production.During first generation, blade produces yellow point, then expands and develops into circle or oval scab, and the mould layer of the raw adularescent powdery in surface, be conidiophore and the conidium of germ, rear scab flavescence brown is the cleistothecium of germ.Mildew is disperseed separately in early days, after be unified into a large mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, causes early ageing, output incurs loss.
In the control of powdery mildew, mainly rely on the bactericide such as benzimidazole, triazole type.These medicaments are because Long-Time Service has created pesticide resistance in various degree, and control efficiency reduces.Especially triazole type medicament has inhibitory action when using dosage is large to the growth of crop, easily causes poisoning.
Metrafenone, english common name: metrafenone is Benzophenones new type bactericide, molecular formula C

5, effectively can prevent and treat cereal, the powdery mildew of melon and fruit and vegetables.But the production that metrafenone is current and use cost all higher, and be used alone for a long time and also have very large resistance risk.
Summary of the invention
The object of this invention is to provide a kind of synergistic effect obvious, to the bactericidal composition that powdery mildew control efficiency is good, cost is low, resistance risk is low.
Another object of the present invention is to provide the application of this bactericidal composition.
Inventor by a large amount of indoor biometricses and field control effectiveness test, surprisingly finds metrafenone and the third oxygen quinoline in certain proportion after mixture, has significant synergistic effect to diseases such as powdery mildews.
Described third oxygen quinoline: English name proquinazid, molecular formula C

Compared with prior art, its advantage is in the present invention: 1, composition synergistic effect is obvious, and preventive effect significantly improves compared with single dose; 2, after drug effect improves, the effective ingredient consumption in field declines, and reduces production and use cost, decreases residue of pesticide and environmental pollution; 3, composition is made up of the active ingredient of different mechanism of action, and action site increases, and is conducive to overcoming and delay the drug-fast generation of germ.
Embodiment
Being undertaken composite by the pesticide active ingredient of different types of structure, is a kind of effective means solving the problem such as cost and resistance in agricultural chemicals single dose application process at present.After the pesticide active ingredient mixing of different types of structure, usually show three kinds of type of action, i.e. summation action, synergistic effect and antagonism, but be specially which kind of effect, unpredictable, only have and just can be known by lot of experiments.Compound synergic is well filled a prescription, and can improve actual control efficiency, and reduce the usage amount of agricultural chemicals, contributing to the generation of delaying drug resistance, is the important means of scientific prevention and cure damage by disease and insect.
The present composition has obvious synergistic function to Powdery Mildew etc., and is not only the simple addition of two kinds of pharmacy effects, is clear that very much this result can tested from following Toxicity Determination.
Assays Example: composition is tested the Toxicity Determination of cucurbits powdery mildew bacterium
Subjects is wheat powdery mildew (Erysiphe graminis).
Test method: with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T 1156.4-2006 ".Choose the potted plant three leaf one heart stage wheat seedlings that growing way is consistent, 5 basins are selected in each process, number for subsequent use.Spray under 50PSI pressure with Potter spray tower, every basin 5mL.Test process is see table 1, table 2, and each medicament arranges 5 concentration gradients.Carry out after 24h trembling powder inoculation wheat powdery mildew conidium.To spray the wheat seedling of equivalent clear water for blank.After inoculation, wheat seedling is put into greenhouse to cultivate.After 7d, according to the morbidity grade scale investigation disease index of wheat powdery mildew, and calculate control efficiency.
Wheat powdery mildew severity Scaling standard:
0 grade: blade is without scab;
1 grade: lesion area accounts for less than 5% of whole blade area;
3 grades: lesion area accounts for 6% ~ 10% of whole blade area;
5 grades: lesion area accounts for 11% ~ 25% of whole blade area;
7 grades: lesion area accounts for 25% ~ 50% of whole blade area;
9 grades: lesion area accounts for more than 50% of whole blade area.
The expection effect (i.e. theoretical control efficiency, %) of mixture of active principles uses Colby formula to determine and compares with the effect observed:
Colby formula: E=X+Y-X*Y/100
E: when active components A working concentration in composition is a, compositions contemplated effect when active component B working concentration is b.
X: effect when active components A using dosage is a.
Effect when Y: active component B using dosage is b.
Illustrate that mixture has synergistic effect when the actual control efficiency observed exceedes expection preventive effect.
Toxicity test result see table 1 to table 2.
The independent reactive compound of table 1 is to the pot experiment measurement result of wheat powdery mildew
Table 2 metrafenone and the composite pot experiment measurement result to wheat powdery mildew of the third oxygen quinoline
Result of the test shows, metrafenone and the third oxygen quinoline composite control wheat powdery mildew within the specific limits, has synergistic effect.
