Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of highly effective pesticide composition on crop pest that contains mepanipyrim.
Technical background
Mepanipyrim, English name: mepanipyrim, molecular formula: C
14H
13N
3, mepanipyrim is the miazines bactericide, and mepanipyrim has the secretion that unique mechanism of action namely suppresses pathogen protein, comprises reducing some hydrolase levels, and these enzymes and pathogen enter host plant and cause the histozoic necrosis of note by inference.
The mould prestige of second, English name: diethofencarb, molecular formula: C
14H
21NO
4, chemical name: 3,4-diethoxy phenylcarbamic acid isopropyl ester.Systemic fungicide suppresses the formation of botrytis cinerea gemma spindle, and a kind of and carbendazim has the bactericide of secondary cross resistance.Medicament enter behind the somatic cells with somatic cells in tubulin binding, thereby affect the division of cell.This mode of action is very similar to carbendazim, but the two is not at same application point.In a single day carbendazim is developed immunity to drugs such as botrytis cinerea, and very sensitive to the mould prestige of second.On the contrary, to the botrytis cinerea of carbendazim sensitivity, the mould prestige of second then shows as without bacteriostatic activity.
Iprodione, English name: iprodione, molecular formula: C

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.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.
Mepanipyrim and active component B(B are selected from a kind of of the mould prestige of second, iprodione, procymidone, dithianon) composite to the crop pest Toxicity Determination.
After each medicament establishment concentration range was determined in prerun, each 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
Control group net growth-processed group net growth
Mycelial growth inhibition rate (%)=---------------* 100
The control group net growth
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
