The composition has relatively high activity on various diseases of various crops and has an obvious synergistic effect, and the bactericidal spectrum is enlarged. The composition has characteristics of small dosage, rainwash resistance and obvious synergism.
Description
Technical field
The invention belongs to technical field of pesticide, relate to and a kind ofly contain iprovalicarb Yu the application of the bactericidal composition of famoxadone on crop pest.
Technical background
Iprovalicarb (iprovalicarb); chemical name: 2-methyl isophthalic acid-[(1-p-methylphenyl ethyl) carbamoyl]-(S)-propyl carbamic acid isopropyl ester; it is a kind of amino acids bactericide; the mechanism of action is the amino acid whose metabolism of impact; different from known biocides, with the bactericide such as metalaxyl without cross resistance.Iprovalicarb is by the growth that suppresses sporangium plumule pipe, mycelial growth and sporulation two performances protection, the therapeutic action to crop.Can effectively prevent and treat the microbial disease of Oomycete cause of disease.
In the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the generation of disease drug resistance.The different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.Reduce the risk that plant pathogenic fungi develops immunity to drugs, it is one of way of at present normal employing that the application synergistic composition is prevented and treated the noxious plant disease fungus.

Application Example two:
For trying disease: downy mildew of garpe, test medicine provides by the applicant, experimental scheme: the establishment concentration range of determining the two different proportioning mixture of iprovalicarb from famoxadone through preliminary experiment.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.First by Toxicity Determination, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR＜0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect, on this basis, carry out field trial again.
Test method: after each medicament establishment concentration range was determined in prerun, medicament was established respectively 5 dosage by active constituent content and is processed, and established the clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt the mycelial growth rate method to measure medicament to the virulence of crop germ.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates thus the EC of every kind of medicament
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active components A Yu famoxadone shared ratio in combination;
A is iprovalicarb;
The B famoxadone.
Toxicity test result
Table 1 iprovalicarb is Yu the composite toxicity test analysis of results table to downy mildew of garpe of famoxadone
As shown in Table 1, iprovalicarb Yu the composite proportioning of downy mildew of garpe of preventing and treating of famoxadone at 1: 80～60: 1 o'clock, synergy ratio SR is all greater than 1.5, illustrating that both were mixed in the scope at 1: 80～60: 1 all shows synergistic effect, iprovalicarb Yu the proportioning of famoxadone at 1: 30～10: 1, synergistic effect is more outstanding.Test the discovery iprovalicarb Yu the proportioning of famoxadone is 10: 1,5: 1,4: 1,3: 1,2: 1,1: 1,1: 2,1: 3,1: 4,1: 5,1: 6,1: 7,1: 8,1: 9,1: 10,1: 11,1: 12,1: 13,1: 14,1: 15,1: 20,1: 25,1: 30 through the applicant, wherein iprovalicarb and famoxadone weight ratio are that 1: 2 o'clock synergy ratio is maximum, and synergistic effect is the most obvious.
The effect experiment result: test medicine is researched and developed, is provided by the applicant, contrast medicament 10% iprovalicarb wetting powder (autogamy), 10% famoxadone wetting powder (autogamy).
Application Example one iprovalicarb is Yu famoxadone and the composite control cucumber downy mildew test of pesticide effectiveness thereof
This experimental establishment is investigated the cucumber downy mildew state of an illness in the Pucheng County, Shaanxi Province before the medicine, in for the first time dispenser of state of an illness initial stage, dispenser in per 7 days once is total to dispenser 2 times.Investigated respectively disease index and calculated preventive effect in 7 days, 14 days, 30 days after for the second time dispenser.Experimental result is as follows:

Application Example three iprovalicarbs are Yu famoxadone and the composite downy mildew of garpe test of pesticide effectiveness of preventing and treating thereof
This experimental establishment is investigated the downy mildew of garpe state of an illness at Shaanxi Province's Weinan City before the medicine, in for the first time dispenser of state of an illness initial stage, dispenser in per 7 days once is total to dispenser 2 times.Investigated respectively disease index and calculated preventive effect in 7 days, 14 days, 30 days after for the second time dispenser.Experimental result is as follows:
Table 4 iprovalicarb is Yu famoxadone and the composite downy mildew of garpe test of pesticide effectiveness of preventing and treating thereof
As can be seen from Table 4, iprovalicarb Yu famoxadone and composite after can effectively prevent and treat downy mildew of garpe, simultaneously anthracnose of grape is also had good preventive effect, control efficiency all is better than the preventive effect of single dose, and the preventive effect phase is long.In the test scope of medication, the target crop is had no adverse effects.
Application Example four iprovalicarbs are Yu famoxadone and the composite wheat rust test of pesticide effectiveness of preventing and treating thereof
This test arrangement is investigated wheat rust at Shaanxi Province's Weinan City before the medicine, in for the first time dispenser of state of an illness initial stage, dispenser in per 7 days once is total to dispenser 2 times.Investigated respectively disease index and calculated preventive effect in 7 days, 14 days, 30 days after for the second time dispenser.Experimental result is as follows:
Table 5 iprovalicarb is Yu famoxadone and the composite wheat rust test of pesticide effectiveness of preventing and treating thereof
As can be seen from Table 5, iprovalicarb Yu famoxadone and composite after can effectively prevent and treat wheat rust, simultaneously wheat net blotch, glume blight are had good preventive effect, control efficiency all is better than the preventive effect of single dose, and the preventive effect phase is long.In the test scope of medication, the target crop is had no adverse effects.
