Two, bioactive mensuration
In order to further appreciate that the virulence of sulfur insect amide and clothianidin compositions, carry out a large amount of formulation screening test.
Pesticidal combination biological activity determination of the present invention is as follows:
Infusion process is used to process tea lesser leafhopper (Empoasca pirisuga Matumura), according to pesticide room
Interior bioassay test criterion (agricultural industry criteria NY/T1154.7-2006) and initiative pesticide bioactivity evaluate SOP (parasite killing
Agent is rolled up), measure single dose LC50With mixture LC50。
Brown Planthopper (Nilaparvata legen) selected by target, indoor throughout the year by rice seedling raising worm kind (27
DEG C, 14h illumination/d).Indoor feeding is selected to be for experiment to the larva that 3 mid-terms age are consistent.Use nebulization.Test Oryza sativa L. children
Seedling selects water culture to cultivate the rice seedling (being about 3～4cm) to 2 leaf 1 hearts, cleans standby with clear water.By 4～6 rice seedlings
It is fixed in the culture dish of Φ 7cm with Quartz Album sand, connects Brown Planthopper 3 larva in mid-term in age 30 of CO2 anesthesia, be placed in
Quantitative (2.5mL) spraying treatment (pressure is 5Ib/iW2, and settling amount is 4.35mg/cm2) under Potter spray tower, test sets not
Corresponding organic solvent containing medicament is processed as comparison, often processes and is repeated 4 times, covers with transparent plastic cup, be put in temperature after spraying
Observe indoor illumination 14h for 27 DEG C, check result after 3d, touch polypide with brush pen, reactionless be considered as dead worm.Add up what each processed
Live borer population and total borer population, calculate the mortality rate of each process and corrected mortality (Abbott ' s formula)；With " DPS data process system
System " V14.50 professional version carries out data analysis statistical, obtains regression straight line, LC50Value.Calculate by the abundant method of Sun Yun (Sun etc., 1960)
Toxicity index, is calculated co-toxicity coefficient by following formula:
Toxicity index × the A of theoretical mixed toxicity index (TTI)=A content (%) in mixed
Toxicity index × the B of+B content (%) in mixed
When co-toxicity coefficient is more than 120, show that this mixture has potentiation；And co-toxicity coefficient less than 80 time, show
This mixture has antagonism；And co-toxicity coefficient more than 80 less than 120 time, show that this mixture has summation action.
HY366 and MTI-446 different ratio mixture the results are shown in Table 1 to the Toxicity Determination of planthopper
