Description
Technical field
The invention belongs to technical field of pesticide, specifically relate to a kind of composition pesticide containing the control crops root-knot nematode of fosthiazate and clothianidin.
Background technology
Meloidogyne omnivorousness plant pathogeny line insect, all also exists toxic action for crops, vegetables and fruit tree.Existing market is for the control of root-knot nematode mainly based on fosthiazate and Avermectin, and formulation is single, and residue of pesticide are serious.Fosthiazate belongs to organic phosphates nematocide, and its mode of action is to suppress the harm of the synthesis control root-knot nematode of root-knot nematode acetylcholinesterase.But, in the process of preparation dispenser, the use of fosthiazate is spread fertilizer over the fields based on soil and fills with root.Therefore, very limited to the producing level of agricultural chemicals, and the residue of pesticide caused also are CR Critical.So the present invention is by fosthiazate and clothianidin matched combined, and expand control spectrum, reduce the unit usage amount of agricultural chemicals, action pathway, action effect all make moderate progress.
Chinese patent CN201210267789.8 discloses a kind of insecticides containing fosthiazate and clothianidin, but its crop object is wheat aphid, cotton aphid, the yellow bent flea beetle of vegetables etc., does not study the control of root-knot nematode.And insecticide has for different types of insect and significantly distinguishes effect, through inventor's research, find that the present composition is applied to control crop root-knot nematode and has good synergistic effect after composite.

Application Example two
The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.
First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, on this basis, then carry out field trial.
Test method: choose by the capsicum root system of seriously causing harm, running water slowly cleans up, capsule is warmed up by milky in dissecting needle picking old complaint, put into the culture dish of diameter 6cm, add a small amount of sterile water, hatch 3 ~ 5 days in 20 degree of insulating boxs, collect 2 instar larvaes, and adding sterile water, to be configured to finite concentration (500/about ml) suspension for subsequent use.
Setting organizes concentration gradient, using sterile water as blank more.Get medicament 100 microlitre that the 96 every holes of porocyte culture plate add the variable concentrations prepared, add isopyknic root-knot nematode suspended emulsion again, under 20 degree of conditions, moisturizing is cultivated, the amount of survival of root-knot nematode 2 instar and dead quantity is checked respectively at the different time handled well, root-knot nematode presents and stiffly motionless is dead worm, and what present bending wriggling state is worm alive.Calculate lethality and corrected mortality.
According to survey data, the corrected mortality of computing.The abundant method of Sun Yun is adopted to calculate the co-toxicity coefficient (CTC value) of mixture with reference to NY/T1154.1-2006.If contrast lethality <5%, does not correct; Contrast lethality, between 5% ~ 20%, corrects; Contrast lethality >20%, test of reforming.Be independent variable x with the logarithm value of concentration (mg/L), to correct lethality value for dependent variable y, setting up virulence regression equation is respectively, adopts DPS software to calculate LC50, LC90 and the mixture co-toxicity coefficient thereof of single dose and each mixing ratio, compares synergy situation.
Computing formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation, and calculate the value of often kind of medicament thus with method of least squares.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (take fosthiazate as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=fosthiazate of M
fosthiazatetI × the P of+effective clothianidin
clothianidin
In formula: M is the mixture of different ratio
P
clothianidinfor the ratio that effective clothianidin is shared in the composition
P
fosthiazatefor the ratio that fosthiazate is shared in the composition
B is selected from clothianidin.
For examination insect: root-knot nematode
Experimental scheme: through effective lethal concentration scope of preliminary experiment determination fosthiazate and the former medicine of clothianidin and the two different ratio mixture.
