Description
Technical field
The present invention relates to technical field of pesticide combination, being specifically related to a kind of is the composite insecticidal and bactericidal composition of active ingredient two yuan containing agricultural chemicals Imicyafos and bupirimate.
Background technology
Imicyafos (AKD-3088) is a kind of cyanamide heterocyclic organic matter, it is combined by the sub-imidazolidine of cyano group of asymmetric organic phosphor and nicotinic insecticide, can be used for the crops such as radish, carrot, strawberry, eggplant, tomato, cucumber, muskmelon, watermelon, sweet potato and potato, its chemical structural formula is:
Bupirimate belongs to miazines systemic fungicide, has protection and therapeutic action.Can be absorbed rapidly by plant roots, stem, leaf, and in plant corpus, run to each position, therefore resistance of rainwater washing against.Have that consumption is few, efficient, low toxicity, have the advantages such as special efficacy to powdery mildew, therefore instead of the agricultural chemicals such as the phonetic phenol of second and dimethirimol.Be suitable for ornamental plants, the field crops such as fruit tree, vegetables, flowers.The various powdery mildew of controlling object, as apple, grape, cucumber, strawberry, rose, sweet Lay powdery mildew, has poisoning to some kinds such as strawberry, apple, roses.Its chemical structural formula is:
The insecticide that Long-Time Service is single or bactericide, insect or germ are easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field are more single.The different mechanism of action and without the insecticide of cross resistance and bactericide rational mixture by a certain percentage, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively the pesticide resistance of reduction crop.Summary of the invention
According to the deficiencies in the prior art; the present invention proposes a kind of Fungicidal insecticidal composition containing bupirimate, said composition contains A, B two kinds of effective active components, and component A selects novel pesticide Imicyafos; B is selected from bupirimate; it is wide that the present composition has effect field, can desinsection again can sterilization, and consumption is few; preventive effect is high; residual few, the lasting period is long, is conducive to environmental protection.
The present invention be a kind of with novel pesticide Imicyafos and bupirimate for active ingredient carries out the insecticidal and bactericidal composition preparation of two yuan of mixtures, wherein in insecticidal and bactericidal composition of the present invention, the ratio of weight and number of active ingredient novel pesticide Imicyafos and bupirimate is 1 ~ 50: 50 ~ 1, on the basis of test recipe screening targetedly, the ratio of weight and number of active ingredient novel pesticide Imicyafos and bupirimate can be preferably 3 ~ 25: 25 ~ 5.

Field experiment: to the control of Wheat Diseases And Insect Pests
(1) experimental field basic condition:
Experimental field be located at Henan, the wheat paddock selecting occurring degree medium is that experimental field soil fertility is medium, and irrigation and drainage are convenient.Dispenser weather in March on the same day 31 is clear to cloudy, mean temperature of air 11 DEG C, relative moisture 81%, southerly 2 ~ 3 grades; April 7 was fine day, mean temperature of air 18.2 DEG C, relative moisture 60%, southerly 2 ~ 3 grades.
(2) spraying time and method
At wheat powdery mildew their early stage (March 31) spray the 1st medicine, after 10d, (April 10) spray second time medicine, sprays 2 times altogether.Adopt 3WBS-16 knapsack sprayer (operating pressure 0.2 ~ 0.3MPa), carry out foliar spray according to per hectare amount of liquid medicine 750L.
(3) pilot survey and data processing
Investigation state of an illness radix before medicine, test is investigated 3 times altogether, i.e. disease index investigation before medicine, preventive effect investigation in 10 days after the 1st medicine, 10 days and preventive effect investigation in 20 days after 2 medicines.
(4) drug effect computational methods
Sick leaf rate (%)=sick number of sheets/investigate the total number of sheets × 100
Disease index=∑ (the sick number of sheets × relative level numerical value at different levels)/(investigating the total number of sheets × 9) × 100
Control efficiency (%)=(before 1-(blank district medicine after disease index × treatment region medicine disease index)/(after blank district medicine before disease index × treatment region medicine disease index)) × 100
(5) poisoning investigation method
Whether after dispenser, continuous 7d estimates medicament has poisoning to crop.
(6) experimental result and analysis
The test effect of wheat powdery mildew prevented and treated by table 1 respectively group test medicine process
As can be seen from Table 1, the ratio of weight and number of 30%imicyafos bupirimate is that the effect of the mixture combination control wheat powdery mildew of 12: 18 is very remarkable, and Be very effective is better than single dose, and its quick-acting and lasting effect are all relatively good, especially outstanding with lasting effect.Complex preparation control efficiency under the consumption of high concentration is significantly better than the effect under low concentration consumption.After the 1st, 2 medicine, the best control efficiency of 10 days reaches 90.08% and 92.67% respectively, and after the 2nd medicine, 20 days best preventive effects reach 90.02%.And 20 days best preventive effects are 80.54% after single dose 25% bupirimate SC the 2nd medicine, the Be very effective of complex preparation is better than single dose.According to field range estimation, substantially there is no insect pest with the wheat of 30%imicyafos bupirimate, and growth fraction is more vigorous, and the wheat of 25% bupirimate single dose occurs that insect pest is more, than with the insect pest plant of complex preparation much about about 15%.
In addition within the scope of test dose, plant growth is normal, and the poisoning phenomenon to wheat does not all appear in each treatment agent, illustrates that it is safe to wheat.
