Description
Technical field
The present invention relates to the composition pesticide that a kind of pesticide field has synergistic effect, its active ingredient is cytosintetidemycin and benzimidazole germicide.
Background technology
Virus disease is the important disease of the economic crops such as tomato, capsicum and tobacco, and the annual protection ground and outdoor vegetable cultivation and leaf tobacco production given causes serious production loss.In the chemical control of the viroses of plant, years of researches are carried out both at home and abroad, although some antiviral agents have started to enter practical stage as ZhiBingLing(SIC) etc., but the medicament of chemosynthesis has long, the shortcoming such as cost is high, toxicity is large, environmental pollution is serious of cycle, can not meet the requirement of agricultural sustainable development far away.
Cytosintetidemycin, cytosintetidemycin belongs to cytidine peptide class novel antiviral preparation, is a kind of efficient, low toxicity, nuisanceless type biopesticide.Cytosintetidemycin is that one belongs to the antiviral novel farm antibiotics of cytidine peptide class, it is a kind of microorganism formulation, low toxicity, efficient, noresidue, multiple virus disease is had to good preventive and therapeutic action, especially preventing and treating stripe disease, the virus diseases of the disease of stunting, tobacco mosaic virus disease, each fruit trees and vegetables has remarkable result.Test and show through the field efficacy of national Ministry of Agriculture tissue, cytosintetidemycin is higher by 20% ~ 30% than the drug effect of at present domestic like product.Can effectively suppress the propagation of the plant viruses such as tobacco mosaic virus, cucumber mosaic virus, maize dwarf mosaic virus, oryza virus 3, fractilinea oryzae, there is prevention and the treatment effect of the viroses of plant and the function of adjusting and promotion plant growth.
Benzimidazole germicide is to have the class organic bactericide that the benzimidazole ring of bactericidal activity is parent, nearly all this compounds all shows interior suction bactericidal activity, wherein representative compound has benomyl, carbendazim, blue or green bacterium spirit, thiophanate, thiophanate-methyl is (in plant corpus or plant nearby through metabolism activation, become tolimidazole-2-carbamate, it is carbendazim, or be similar to their compound, thereby show bactericidal activity) and probenazole, furidazol, the spirit of azoles bacterium is (after being absorbed by plants, conduct to infection site, and present bactericidal action) etc.
Benzimidazole germicide has been gone through research for many years, and is widely used.It is serious that the use of the large consumption of high density for many years causes resistance to produce.
Summary of the invention
Because weather is comparatively unusual in recent years, Changes in weather is too fast, causes corps diseases serious, and the frequency of disease development of crop virosis obviously raises, and causes the situation that the significantly underproduction is even had no harvest to occur repeatedly.Too much dispenser is that various sterilization agent produces resistance, and in view of the situation, the present invention proposes a kind of microbicide compositions with synergistic effect and delaying drug resistance appearance.
Object of the present invention is: propose a kind of complex preparation of pesticide field, overcome the above problems.

Duration of test weather is good, and daily mean temperature is 18.0～26.8 ℃.Dispenser fine day on the same day.
Investigation method:
In dispenser Qian Mei community by 5 samplings of diagonal. chosen 20 strains of bacterial blight of rice rice seedling at every.Statistics is demarcated disease index in strain. state of an illness radix before using this as dispenser.After dispenser the 3rd, 7,10d investigates respectively and determines scab spread condition in strain. using scab inhibiting rate as control efficiency.
Bacterial leaf-blight grade scale:
0 grade: anosis;
1 grade: occur yellow scab;
3 grades: occur canescence scab, blade is inwardly curling, lesion area accounts for whole leaf area below 5%;
5 grades: typical scab, lesion area accounts for whole leaf area 6 ~ 25%;
7 grades: typical scab, lesion area accounts for whole leaf area 26 ~ 50%;
9 grades: typical scab, lesion area accounts for whole leaf area more than 50%.
Drug effect computational methods:
Sick number of sheets * l00 before sick leaf decline rate (%)=(the sick number of sheets after the front sick number of sheets-dispenser of dispenser)/dispenser
Preventive effect (%)=(the sick leaf decline rate in the sick leaf decline rate-check plot for the treatment of region)/(sick leaf decline rate in 100-check plot) * 100
table 1 is respectively processed bacterial blight of rice control efficiency field experiment
Measurement result shows, cytosintetidemycin and carbendazim, in the time that proportioning is 3:12, are obviously better than cytosintetidemycin and carbendazim single dose control efficiency for the control efficiency of bacterial blight of rice, significant for increasing production of rice.
Test the field experiment of 2 cytosintetidemycins and thiophanate-methyl complex preparation control tobacco virus
Test method:
Tested on October 8th, 2010 to October 18 and carry out in Dali of Yunnan suburban area tobacco planting garden.Tested on October 8th, 2010 and carry out routine to water spray by each processing design concentration.Spraying equipment is WF-16 type knapsack hand sprayer, and shower nozzle is single fan nozzle, and operating pressure is 0.2-0.4Mpa, and spray amount is 0.36-0.48L/min, carries out routine spraying, makes every effort to evenly thoughtful when spray medicine.
Duration of test weather is good, and daily mean temperature is 18.0～26.8 ℃.Dispenser fine day on the same day.
Investigation method:
In dispenser Qian Mei community by 5 samplings of diagonal. chosen 20 strains of tobacco virus plant at every.Statistics is demarcated disease index in strain. state of an illness radix before using this as dispenser.After dispenser the 3rd, 7,10d investigates respectively and determines the sick number of sheets in strain, calculates preventive effect with sick number of sheets decline rate.
Drug effect computational methods:
Sick number of sheets * l00 before sick leaf decline rate (%)=(the sick number of sheets after the front sick number of sheets-dispenser of dispenser)/dispenser
Preventive effect (%)=(the sick leaf decline rate in the sick leaf decline rate-check plot for the treatment of region)/(sick leaf decline rate in 100-check plot) * 100
table 2 different disposal is prevented and treated measurement result to tobacco virus
Show by above field experiment, cytosintetidemycin and thiophanate-methyl complex preparation are obviously better than single dose for the preventive effect of tobacco virus, and occur without poisoning situation, significant for agricultural produce, are worthy to be popularized.
