(2) the indoor biological determination of activity of the present composition and field efficacy checking.
1st, fluxapyroxad, diethyl aminoethyl hexanoate and Tebuconazole and its complex composition are surveyed to the indoor co-toxicity of rice sheath blight disease
It is fixed.
The test method of indoor biometricses：Reference standard NY/T1156.6-2006, medicament is determined to water using growth rate method
The inhibitory action of Thanatephoruscucumeris mycelial growth.On the basis of pilot study, germ mycelial growth is suppressed from each medicament
Rate is up to 5 concentration of design in the range of 10%~90%, first by 95% fluxapyroxad active compound and 97% Original Tebuconazole with acetone
It is standby that the decoction of series concentration is made into for solvent, decoction then is added into oneself in 1% ratio melts and be cooled to 35 DEG C or so
PDA culture medium in, after fully shaking up, pour into the culture dish (diameter 90mm) of sterilizing be made band medicine flat board, often handle four times
Repeat, to add the processing of sterilized water as blank control；With card punch (diameter 5mm) picking Rhizoctonia solani Kuhn bacterium of sterilizing
Cake, the face-down aseptic inoculation of mycelia are inverted in 25 DEG C of constant incubator and cultivated, adopted after cultivating 5d in the center with medicine flat board
Colony diameter is measured with crossing method, calculates EC of each medicament to pathogen50, and calculate virulence according to the following equation and refer to
Number, compare the virulence and bacteriostasis of different agents.
Statistical analysis is carried out with DPS statistical analysis softwares, calculates the EC of each medicament50, and mixture is calculated according to the abundant methods of Sun Yun
Co-toxicity coefficient (CTC values).
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100.
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
The co-toxicity coefficient criteria for classifying：Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 table
It is now antagonism；80 ＜ co-toxicity coefficients (CTC) ＜ 120 show as summation action.
The indoor co-toxicity of table 1, fluxapyroxad, diethyl aminoethyl hexanoate and Tebuconazole and its complex composition to rice sheath blight disease
Measure
As it can be seen from table 1 Tebuconazole and fluorine amine are (by fluxapyroxad and diethyl aminoethyl hexanoate by weight 5:1 composition) 20:
1-1:In the range of 20 (by weight) during compounding use, it spends coefficient (CTC) together more than 120, shows it to rice sheath blight disease
Preventing and treating has synergy synergy, especially in proportioning 5:1 synergistic effect is the most notable.
2nd, the complex composition of fluxapyroxad, diethyl aminoethyl hexanoate and Tebuconazole is imitated in field control rice sheath blight disease and tested
With the lab scale sample of embodiment 1 to embodiment 6, prevent and treat the field test of rice sheath blight disease, by with fluorine azoles
The Contrast on effect of bacterium acid amides and Tebuconazole single dose, and 30% diethyl aminoethyl hexanoate fluxapyroxad water dispersible granules (5% diethyl aminoethyl hexanoate+
25% fluxapyroxad), 41.6% diethyl aminoethyl hexanoate tebuconazole water dispersible granule (Tebuconazole of 1.6% diethyl aminoethyl hexanoate+40%), 60% fluorine
Azoles bacterium acid amides tebuconazole water dispersible granule (Tebuconazole of 10% fluxapyroxad+50%), verifies the synergy after its ternary built
Effect.Test site is high peace certain farming rich and influential family in Jiangxi, test medicine, comparison medicament and the processing of the cell of blank control using with
Machine is arranged, and isolation strip is set between testing per cell.Field banded sclerotial blight when dispenser on June 6 in 2016, dispenser is tested not send out
It is raw, without rainfall in 24 hours after experiment.Plot area:60 ㎡ or so.Number of repetition:3 repetitions.Compressed using back-pack electric
Sprayer, 10 DEG C~28 DEG C of temperature during experiment, suitable banded sclerotial blight occur.
State of an illness radix is investigated before dispenser, is respectively once investigated within 7,14 days after first time medicine.
Efficacy survey method：According to rice leaf sheath and blade damage symptom grading, in units of strain, per 5 points of cell
Accidental sampling, 50 plants of rice of every investigation, record disease series and diseased plant number at different levels, record total strain number, diseased plant number and sick series.
0 grade：Complete stool is disease-free；
1 grade：Quaterfoil and its following leaf sheath, blade morbidity are (using top as first leaf)；
3 grades：Third blade and its following leaf sheath, blade morbidity；
5 grades：Second blade and its following leaf sheath, blade morbidity；
7 grades：Sword-like leave blade and its following leaf sheath, blade morbidity；
9 grades：Complete stool falls ill, withered ahead of time.
Prevention effect (%)=[(CK1- PT1)/CK1]×100
In formula:CK1Disease index after the dispenser of-blank district；
PT1Disease index after the dispenser of-chemicals treatment district.
Table 2, fluxapyroxad, the built composition for preventing and controlling rice sheath blight disease field control effectiveness test of diethyl aminoethyl hexanoate and Tebuconazole
Being drawn according to table 2, after fluxapyroxad, diethyl aminoethyl hexanoate and Tebuconazole compounding, 7 days preventive effects reach 82% after medicine,
And fluxapyroxad single dose 7 days preventive effects after medicine first are 69.47%, the preventive effect of Tebuconazole single dose is 68.65%, diethyl aminoethyl hexanoate list
The preventive effect of agent is 27.92%, it is seen that has good synergistic effect after three kinds of active ingredient compoundings.Compared to fluxapyroxad and amine
Fresh ester compounding, diethyl aminoethyl hexanoate and Tebuconazole compounding, fluxapyroxad and Tebuconazole compound, and also have after three kinds of active ingredient compoundings obvious
Synergy.And 14 days after medicine, the complex preparation of embodiment 1 to embodiment 6 has exceeded 87% to the preventive effect of rice sheath blight disease,
It can be seen that preparation extends to the lasting period of rice sheath blight disease controlling after fluxapyroxad, diethyl aminoethyl hexanoate and Tebuconazole compounding compounding, preventing and treating
Effect is more longlasting.Rice mass of 1000 kernel significantly improves about 6%, and rice yield increases.
