Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a sterilization composition containing oxathiapiprolin and phenoxyquinoline.
Background
The fluorothiazolepyrietophenone is the first piperidyl thiazole isoxazoline bactericide developed by DuPont, has unique action sites on oomycete pathogenic bacteria, and achieves the bactericidal effect by inhibiting oxysterol binding protein (OSBP). It has effects of preventing, treating and inhibiting spore production; it has no cross resistance with the existing bactericide. However, the fluorothiazole pyrithylone has a single action site, has medium-high level resistance risk and needs to be subjected to resistance management.
The quinoxyfen is a systemic fungicide, has special effect on preventing and treating powdery mildew of grains, can quickly permeate into plant tissues and transfer to the top after being applied to leaf surfaces, and has a lasting period as long as 70 days. Has no cross resistance with the existing bactericides on the market, such as triazoles, methyl hydrogen acrylate and the like. The dosage of the composition for preventing and treating wheat powdery mildew is 100-250g (a.i.)/hm 2; the dosage for preventing and treating grape powdery mildew is 50-75g (a.i.)/hm2
Practice proves that the chemical pesticide single agent is easy to have resistance problem after long-term use, so that the dosage is continuously increased, the risk is increased, and the environmental ecological safety is not facilitated. The scientific and reasonable pesticide compounding is a better method for solving the problem. Compounding the pesticide active ingredients with different structure types is an effective way for solving the problems of cost, resistance and the like in the application process of a single pesticide at present. The pesticide active ingredients with different structure types usually show three action types, namely additive action, synergistic action and antagonistic action after being mixed, but the specific action cannot be predicted and can be known only through a large number of tests. The compound synergistic formula is good, can improve the actual prevention and treatment effect, reduces the using amount of pesticides, is beneficial to delaying the generation of resistance, and is an important means for scientifically preventing and treating plant diseases and insect pests.
Disclosure of Invention
In order to overcome the defects of large dosage of medicament, serious environmental pollution, high generation speed of germ resistance and the like of the single bactericide, the invention aims to provide the agricultural bactericidal composition which has reasonable components, obvious synergistic effect, good bactericidal effect, low medication cost, difficult generation of drug resistance and safety to crops.
The technical scheme provided by the invention is as follows:
a sterilization composition containing oxathiapiprolin and phenoxyquinoline is prepared by compounding the active ingredients including oxathiapiprolin and phenoxyquinoline.

Preferably, the weight ratio of the fluorothiazole pyrithylone to the phenoxyquinoline is 1:3-3: 1.
The invention also provides a pesticide preparation containing the bactericidal composition, wherein the weight of the fluorothiazole pyrithylone and the phenoxyquinoline accounts for 10-90% of the total weight of the pesticide preparation, and the balance is an auxiliary agent, a solvent or a filler acceptable in pesticides.
Preferably, the weight of the fluorothiazole pyrithylone and the phenoxyquinoline accounts for 20-60% of the total weight of the pesticide preparation, and the balance is an auxiliary agent, a solvent or a filler acceptable in pesticides.
Preferably, the pesticide preparation is in the dosage form of wettable powder, water dispersible granules, suspending agents, microcapsule suspending agents, powder, granules or aqueous emulsion and the like.
The adjuvants used in the pesticide preparation of the present invention include solvents, dispersants, emulsifiers, stabilizers, antifreezes, film formers, wetting agents, and the like, and other known substances useful for stabilizing the active ingredients in the preparation and exerting the medicinal effects, are various ingredients commonly used or allowed to be used in the pesticide preparation, are not particularly limited, and the specific ingredients and amounts thereof are determined by simple experiments according to the formulation requirements.
The bactericidal composition is applied to preventing and treating various diseases of crops such as wheat and the like, and is particularly suitable for preventing and treating powdery mildew. The compositions of the invention can also be applied in the usual manner, for example by pouring, spraying, spreading, the application rate varying with weather conditions or crop conditions.
Compared with the prior art, the invention has the following beneficial effects:
the composition has obvious synergistic effect when mixed; because the two single agents of the composition have great difference in chemical structure and completely different action mechanisms, the composition has no cross resistance and can delay the resistance problem caused by the single use of the two single agents; the composition of the invention is safe to crops and has good control effect. Experiments prove that the bactericide composition has stable chemical properties and obvious synergy, and shows obvious synergy and complementary action on a control object.
Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Example 1 indoor toxicity assay test object of combinations of fluthiazopyranone and phenoxyquinoline on wheat powdery mildew: powdery mildew of wheat
The test is carried out by pot culture method, after wheat seeds are germinated, the wheat seeds are planted in a sterilized soil culture bowl and cultured at room temperature. When the seedlings grow to 1 leaf per heart stage, putting the seedlings into a 20 ℃ illumination incubator, and alternately culturing in light and dark for 12 hours. Fresh wheat powdery mildew spore suspension is sprayed on the standby wheat seedlings, and 15 strains are sprayed in each 2 pots of treatment. Treating with the preparation 72h after inoculation, investigating the disease index of each treatment before the preparation, investigating the disease index every 5d after the preparation, and calculating the prevention effect until all diseases are attacked. Statistical analysis was performed using the DPS data processing software to calculate the EC50 for each agent, followed by the Sun Yunpei method to calculate the cotoxicity coefficient (CTC). The specific measurement results are shown in Table 1.
When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Observed virulence index (ATI) ═ standard agent EC 50/test agent EC50 × 100
Theoretical virulence index (TTI) ═ A percent virulence index × of agent(s) and + B percent virulence index × of agent(s)
