Abstract
The invention relates to a fungicidal composition containing bromothalonil and propineb and application thereof, wherein the weight part ratio of the bromothalonil to the propineb as active components is 20:1 to 1:100, and the weight percentage of the active components in the composition is 1 percent to 90 percent. The fungicidal composition, which is used to control crop diseases caused by pathogenic fungi, not only has a synergistic effect and reduces the usage cost of farm chemical, but also can greatly delay the development speed of the resistance of pathogenic fungi and prolong the service life of the chemical.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of bromothalonil and composite bactericidal composition of Propineb of containing, be used for preventing and treating the plant disease that causes by disease fungus, as the downy mildew on the crops such as cereal, melon and fruit, vegetables, eqpidemic disease, anthracnose, powdery mildew, rust etc.
Technical background
Bromothalonil (Bromothalonil), chemical name are 2-bromine 2 bromomethyl glutaronitriles, are a kind of new and effective bactericide, can be absorbed rapidly by somatic cells, and its normal development of Conduction Interference in cell, thus reach effect antibacterial, sterilization.Bromothalonil toxicity is low, safe, the bromothalonil that is three times in working concentration is also gentleer than soap to the excitant of human body skin, and its fungicidal spectrum is wide, the scope of application is wide, and multiple fungi and some bacterial diseases of Mastigomycotina, Ascomycotina, Deuteromycotina all had better inhibition, killing action.The practice of bromothalonil is used and is shown, it not only can controlling plant diseases, reduces production loss, and this medicament itself has simultaneously stimulates the activity of making plurality of enzymes in the object, increases photosynthesis, makes plant leaf look dark green, healthy and strong, improves crop quality and output.
Bromothalonil can be good at suppressing and rooting out germ, is a kind of outstanding bactericide, but long-term a large amount of single uses cause germ that it is produced resistance and preventive effect is reduced greatly unavoidably.
Propineb (P r o pi neb), chemical name acrylic bisdithiocarbamic zinc is a kind of protective fungicide of quick-acting, long residual, wide spectrum.Its bactericidal mechanism is unfixing, and site of action is many, mainly suppresses the oxidation of pyruvic acid in the cause of disease thalline.It has the better protect activity, but therapeutic activity is not satisfactory, and result of use is not good enough separately.
About bromothalonil and the composite product of Propineb, do not appear in the newspapers as yet both at home and abroad at present.
Summary of the invention
At above-mentioned technical problem, the invention provides a kind of efficient bactericidal composite that contains bromothalonil and Propineb, in order to prevent and treat by the microbial crop pest of cause of disease, not only can play the effect of Synergistic, reduce the agricultural chemicals use cost, and can delay the speed that pathogen develops immunity to drugs greatly, prolong the service life of medicament.
The present invention is achieved through the following technical solutions:
The present invention relates to a kind of bactericidal composition that contains bromothalonil and Propineb, the ratio of weight and number of active ingredient bromothalonil and Propineb is 20: 1～1: 100.As preferably, the ratio of weight and number of Fungicidal active substance bromothalonil and Propineb is 1: 1～1: 20.
The bactericidal composition active component weight percentage that the present invention relates to is 1～90%, add suitable known auxiliary agent and excipient, make the formulation that suitable agricultural is upward used according to the method that those skilled in the art all know, be preferably wetting powder, suspending agent, water dispersible granules.Described known auxiliary agent, excipient have dispersant, diffusant, defoamer, wetting agent, disintegrant etc.
The bactericidal composition that the present invention relates to can be used to prevent and treat the various crop disease, is widely used in the control of the multiple diseases such as downy mildew, eqpidemic disease, anthracnose, powdery mildew, rust on cereal, melon and fruit, vegetables such as wheat, banana, mango, grape, apple, pears, strawberry, lichee, cucumber, custard squash, capsicum, eggplant, potato, tomato, Kidney bean, lettuce, the Chinese cabbage etc. crops.
Beneficial effect of the present invention: the one, with bromothalonil and the composite use of Propineb; can make composite dose to possess very high protection activity simultaneously and treat, root out activity; compare with single agent; can obviously improve preventive effect; prolong the lasting period; thereby dosage, drug cost and lot of manpower and material resources have been saved; not only reach the effect of getting twice the result with half the effort; and owing to reduced the amount of application of agricultural chemicals; the extent of injury to environment also reduces significantly; alleviate the pressure that bears of social environment, thereby had favorable economic benefit, social benefit and environmental benefit.The 2nd, because composite dose bactericidal action site variation can delay the pathogen resistance greatly and take place and the speed of development, help prolonging the service life of outstanding bactericide.
Embodiment
Below in conjunction with embodiment the bactericidal composition of bromothalonil of the present invention and Propineb is described further, but the present invention is not limited thereto.
Give birth to and survey embodiment: the composite toxicity test of bromothalonil and Propineb bacterium of downy mildew of cucumber
Measure the indoor virulence of single, the mixture of bromothalonil and Propineb in indoor employing plate blade method to bacterium of downy mildew of cucumber.Test method: cucumber leaves is placed the culture dish processing of preserving moisture, dosage by design sprays medicament respectively, inoculate bacterium of downy mildew of cucumber after 24 hours, and the cultivation of in incubator, preserving moisture, 7d " Invest, Then Investigate " preventive effect, calculate control efficiency with disease index, carry out statistical analysis with the DPS data processing software, calculate the EC50 of each medicament, adopt the abundant method calculating co-toxicity coefficient of Sun Yun (CTC) to estimate and use effect with, the CTC value has synergistic effect greater than 120 o'clock mixtures, less than 80 o'clock be antagonism, have summation action in the time of between 80～120.
The EC50*100 of the EC50/B agent of toxicity index TI (B)=standard agent A
The EC50*100 of the EC50/AB of actual toxicity index ATI (AB)=A
Theoretical toxicity index TTI (AB)=percentage+TI (B) * B the percentage in mixture of TI (A) * A in mixture
Co-toxicity coefficient CTC=ATI (AB)/TTI (AB) * 100
Result of the test shows, bromothalonil and Propineb are composite, bacterium of downy mildew of cucumber had good indoor virulence, the CTC value of all proportionings is all above 120, show that these two bactericide have good synergistic effects under this proportioning, and when mixed ratio was between 1: 1～1: 20, synergy was particularly remarkable.Experimental data sees the following form 1.
