Specific embodiment
Illustrate whether fluxapyroxad and copper 8-hydroxyquinolinate mixture have synergistic effect below by indoor toxicity test.
1, the synergy of citrus bacterial canker disease is measured.
Using the method for plate culture count, people's sterile water is added to scrape lawn after cultivating 40h on slant medium for examination bacterium
Bacterium solution is made, vibrates 120s through high-speed oscillator, then be diluted to the suspension of about 50/mL of thallus number with sterile water；It will prepare
Reagent agent dilution 2mL move into sterile petri dish, bacterial suspension 1.0mL is accurately added with pipette, then
It is poured into NT culture medium (40-50 DEG C of liquid temperature) 10mL of thawing, shaken cultivation ware is sufficiently mixed medical fluid, thallus and culture medium, coagulates
Gu 16h is cultivated under 25 DEG C of constant temperature after, detects by an unaided eye and counts the single colonie number of each processing；Each drug concentration is arranged 4
It repeats, and blank control is made with sterile water.
Bacterium colony inhibiting rate is calculated as follows:
Bacterium colony inhibiting rate (%)=(control clump count-processing clump count)/control clump count × 100.
Clump count inhibiting rate is converted into probit value, drug concentration is converted into logarithm, find out EC50 with least square method
Value.Then co-toxicity coefficient (CTC) is calculated by Sun Yunpei's Method.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100；
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture in percentage composition+B medicament toxicity index × mixture of A
The percentage composition of B；
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
When CTC≤80, then composition shows as antagonism, and as 80 < CTC < 120, then composition shows as being added and make
With when CTC >=120, then composition shows as synergistic effect.
1 fluxapyroxad of table and copper 8-hydroxyquinolinate combine the indoor toxicity test to citrus bacterial canker disease
The Toxicity Determination result shows: fluxapyroxad is mixed to c itrus canker for 1:80~80:1 with weight ratio with copper 8-hydroxyquinolinate
Disease has preferable virulence, and weight ratio is that 1:60~60:1 shows as synergistic effect, and 1:20~10:1 synergistic effect is especially pronounced.
2, the synergy of citrus scab is measured.
In order to prevent and treat the citrus scab in agricultural production, we have carried out mutual compounding with fluxapyroxad and copper 8-hydroxyquinolinate
Synergy research, subjects be citrus scab (Sphaceloma fawcettii).Raw medicine is configured to the test needed
Medicament, 5 various concentration gradients are arranged in single dose and each Mixed Pharmacy, and (on the basis of preliminary experiment result, bacteriostasis rate is 5%
It is set in the range of~90% by geometric progression).If clear water compares, it is repeated 4 times.
Test uses mycelial growth rate method, is aseptically 5 mm punching with diameter by cultured pathogen
Device cuts bacteria cake from colony edge, and bacteria cake is connected on the culture medium flat plate of different agents concentration with transfer needle, sets 25 DEG C, satisfies
It is cultivated in humidity incubator；When control group bacterium colony covers with, colony diameter is measured, each chemicals treatment is calculated and inhibits mycelia growth
Percentage finds out the EC of each medicament by the linear regression analysis between the probit value of inhibiting rate and the logarithm of series of concentrations50
Value calculates the co-toxicity coefficient (CTC) of mixture with Sun Yunpei's Method, evaluates reagent agent to the activity of germ with this.
The co-toxicity coefficient (CTC) >=120 of compound preparation shows as synergistic effect；CTC≤80 show as antagonism；80 <
CTC < 120 shows as summation action.
2 fluxapyroxad of table and copper 8-hydroxyquinolinate combine the indoor toxicity test to citrus scab
The Toxicity Determination result shows: fluxapyroxad is mixed to citrus scab for 1:80~80:1 with weight ratio with copper 8-hydroxyquinolinate
Disease has preferable virulence, and weight ratio is that 1:60~60:1 shows as synergistic effect, and 1:20~10:1 synergistic effect is especially pronounced.
3, the synergy of apple disease is measured.
In order to prevent and treat the apple disease in agricultural production, we have carried out mutual compounding with fluxapyroxad and copper 8-hydroxyquinolinate
Synergy research, subjects be alternaria leaf spot of apple (Alternaria alternaria f.sp mali), ring rot of apple
(Botryospuaeria berengeriana), canker of apple fruit (Valsa mali), apple marssonina leaf spot (Diplocarpon mali ).Raw medicine is configured to the test medicine needed, 5 various concentration gradients are arranged (pre- in single dose and each Mixed Pharmacy
On the basis of standby test result, bacteriostasis rate is set in the range of 5%~90% by geometric progression).If clear water compares, it is repeated 4 times.

Then application is spaced the 2nd medicine of spray in 12 days.Application is spraying using hand backpack compression sprayer, after each application of guarantee for 24 hours
Without rain, if rain to add in time.It uniformly sprays to blade, fruit, medical fluid is spent to being intended to drip.
State of an illness radix is investigated before application, 15d, 30d carry out final efficacy survey after the 2nd medicine.Every cell investigates 2 plants,
Every plant by the sampling of 5 points of all directions, whole blades of 2 tips of every investigation and 6 fruits.As unit of blade or fruit, disease
Mutual affection grade standard is as follows:
Leaf stage division:
It is 0 grade, disease-free；
L grades, every leaf has scab l-5；
3 grades, every leaf has scab 6-10；
5 grades, every leaf has scab 11-15；
7 grades, every leaf has scab 16-20；
9 grades, every leaf has scab 21 or more.
Fruit stage division:
It is 0 grade, disease-free；
L grades, the connected area of scab accounts for the 5% or less of entire fruit area；
3 grades, the connected area of scab accounts for the 6%~10% of entire fruit area；
5 grades, the connected area of scab accounts for the 11%~25% of entire fruit area；
7 grades, the connected area of scab accounts for the 26%~50% of entire fruit area；
9 grades, the connected area of scab accounts for 51% or more of entire fruit area.
Disease index and control efficiency calculation method:
Disease index=Σ (disease leaf (fruit) numbers at different levels × opposite value of series)/(investigating total leaf (fruit) number × 9) × 100
Control efficiency (%)=(disease index after disease index-chemicals treatment district application after blank district application)/blank control
Disease index × 100 after area's application
