Description
Technical field:
The present invention relates to the composition pesticide that a kind of pesticide field has synergistic effect, its active ingredient is golden caryomycin and benzimidazole germicide.
Background technology:
Virus disease is the important disease of 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 have been carried out both at home and abroad, though some antiviral agents such as ZhiBingLing(SIC) etc. have begun to enter the practicability stage, but the medicament of chemosynthesis has long, shortcoming such as cost is high, toxicity is big, environmental pollution is serious of cycle, can not satisfy the requirement of agricultural sustainable development far away.
The gold caryomycin, be the Shanghai pesticide research developed have efficient, an environmentally safe biogenic pesticide, for the bacterial disease that causes by Xanthomonas campestris (Xanthomonas) better curative effect is arranged, as citrus bacterial canker disease, bacterial leaf streak of rice, bacterial blight of rice etc.Canker for tangerine section plants such as oranges and tangerines, year tangerine, sweet orange, blood orange, oranges has special efficacy especially, and has the greenery restore funcitons.
Gold caryomycin structural formula is:
Benzimidazole germicide is to be a class organic bactericide of parent with the benzimidazole ring that bactericidal activity is arranged, in all showing, inhales nearly all this compounds bactericidal activity, wherein representative compounds 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 plant absorbing, conduct to infection site, and present bactericidal action) etc.
Benzimidazole germicide has been gone through research for many years, and is extensive use of.It is serious that the use of the big 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 of the underproduction significantly even total crop failure to take place repeatedly.Too much dispenser is that the 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.
Purpose of the present invention is: propose a kind of complex preparation of pesticide field, overcome the above problems.
Bactericidal composition active ingredient of the present invention is golden caryomycin and benzimidazole germicide, be used to prevent and treat the viroses of plant, the virus disease that causes as plant viruses such as tobacco mosaic virus, cucumber mosaic virus, maize dwarf mosaic virus, oryza virus 3, fractilinea oryzaes.
Bactericidal composition of the present invention is characterised in that: contain the golden caryomycin of active ingredient (A) and (B) a kind of in the benzimidazole germicide.

Embodiment:
For making technical solutions according to the invention more clear, be illustrated with specific embodiment, but the present invention is not limited only to these examples.
Test 1 field control bacterial blight of rice
Test method:
Tested on October 8th, 2010 to October 18 and carry out at Kaiping City, Guangdong Province suburb truck garden.Tested on October 8th, 2010 and carry out routine to water spray by each processing design concentration.Spraying equipment is a 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 the routine spraying, makes every effort to evenly thoughtful during the 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:
Before dispenser in every sub-district by 5 samplings of diagonal. chosen 20 strains of bacterial blight of rice rice seedling at every.Statistics is demarcated disease index in the strain. with this as dispenser before state of an illness radix.In after the dispenser the 3rd, 7,10d investigates respectively and decides scab spread condition in the strain. with the scab inhibiting rate as control efficiency.
The bacterial leaf-blight grade scale:
0 grade: anosis;
1 grade: yellow scab occurs;
3 grades: the canescence scab occurs, blade inwardly curls, and lesion area accounts for whole leaf area below 5%;
5 grades: typical scab, lesion area account for whole leaf area 6～25%;
7 grades: typical scab, lesion area account for whole leaf area 26～50%;
9 grades: typical scab, lesion area account for whole leaf area more than 50%.
The drug effect computational methods:
The sick leaf sick number of sheets * 100 before rate (%)=(before the dispenser after the sick number of sheets-dispenser the sick number of sheets)/dispenser that goes down
Preventive effect (%)=(the sick leaf rate of going down of treatment region-sick leaf in check plot go down rate)/(the sick leaf in 100-check plot go down rate) * 100
Each handles table 1 bacterial blight of rice control efficiency field experiment
Measurement result shows that golden caryomycin and carbendazim are in proportioning at 3: 12 o'clock, obviously is better than golden caryomycin and carbendazim list agent control efficiency for the control efficiency of bacterial blight of rice, and is significant for increasing production of rice.
Test the field experiment of 2 gold medal caryomycin and thiophanate-methyl complex preparation control tobacco virus
Test method:
Tested on October 8th, 2010 to October 18 and carry out in tobacco planting garden, suburb, Dali, Yunnan Province.Tested on October 8th, 2010 and carry out routine to water spray by each processing design concentration.Spraying equipment is a 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 the routine spraying, makes every effort to evenly thoughtful during the 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:
Before dispenser in every sub-district by 5 samplings of diagonal. chosen 20 strains of tobacco virus plant at every.Statistics is demarcated disease index in the strain. with this as dispenser before state of an illness radix.In after the dispenser the 3rd, 7,10d investigates respectively and decides the sick number of sheets in the strain, calculates preventive effect with the sick number of sheets rate that goes down.
The drug effect computational methods:
The sick leaf sick number of sheets * 100 before rate (%)=(before the dispenser after the sick number of sheets-dispenser the sick number of sheets)/dispenser that goes down
Preventive effect (%)=(the sick leaf rate of going down of treatment region-sick leaf in check plot go down rate)/(the sick leaf in 100-check plot go down rate) * 100
Table 2 different disposal is prevented and treated measurement result to tobacco virus
Show that by above field experiment golden caryomycin and thiophanate-methyl complex preparation obviously are better than single agent for the preventive effect of tobacco virus, and do not have the generation of poisoning situation, significant for agricultural produce, be worthy to be popularized.
