Leaf mold synergistic effect is apparent.Field is estimated, and each processing does not occur to tomato poisoning phenomenon.
2.4 different embodiments prevent wheat scab test result：
2.4.1 test material and method：
Experimental plot is located at Shaoxing, Zhejiang Province city East Lake town Longshan village, and experimental field water and fertilizer condition is preferable, cultivation management condition one
It causes, Pass Test requirement.It is wheat for studying object, kind is Yangmai No.158, plot area 60m2.Experiment sets 15 processing altogether, contains
Clear water compares, and often handles 3 repetitions, cell random alignment.
2.4.2 investigation method, time and number：
In wheat flowering initial stage (about 20%) medication, interval sprays a medicine, continuous dispenser 2 times in 6 days.Every 667 square metres
It is watered 30L, carries out cauline leaf spraying, clear water is sprayed in blank control, and other water and fertilizer managements are consistent with surrounding crop field with insect pest preventing and controlling.
Incidence is managed in (after secondary medicine 25 days) investigation investigation everywhere after wheat scab stable disease.Treatment region is diagonal
5 points of samplings of line, every 50 fringes of investigation, record incidence；According to site of pathological change and hazard rating situation, disease index, meter are calculated
Calculate preventive effect.
2.4.3 drug effect computational methods:
Severity Scaling standard is as follows：
0 grade：Disease-free spot；
1 grade：Sick fringe area accounts for 1/4 or less full fringe area；
2 grades:Sick fringe area accounts for the 1/4~1/2 of full fringe area；
3 grades：Sick fringe area accounts for the 1/2~3/4 of full fringe area；
4 grades：Sick fringe area accounts for 3/4 or more of full fringe area；
Diseased plant rate (%)=diseased plant number/investigation strain number × 100
2.4.4 to the other influences of crop
Observing field diseases, a situation arises and wheat growth situation, observes the influence to Growth of Wheat, plant height, leaf color
Deng whether investigation crop has poisoning, and records poisoning type and extent of injury.
2.4.5 test result and analysis
The different embodiments of table 5. prevent wheat scab test result
2-cyano-3-amino-3-phenylancryic acetate is higher than oxazole to the preventive effect of wheat scab as shown in Table 5, and to small after the two compounding
The preventive effect of wheat head blight is higher than two 25% oxazole missible oil (self-control) of single dose and 25% 2-cyano-3-amino-3-phenylancryic acetate suspending agent (commercially available)
Preventive effect.Wherein, the preventive effect of six embodiments of embodiment 3,4,6,11,12,14 improves the most apparent, illustrates oxazole：
2-cyano-3-amino-3-phenylancryic acetate=20:1—1:It is ideal to the preventive effect of wheat scab when in 20 ranges.It is estimated according to field, in experiment agent
It measures in range, plant growth is normal, and each treatment agent does not occur the poisoning phenomenon to wheat, illustrates that it is safety to wheat
's.Therefore, oxazole is feasible and rational in the prevention of wheat scab with 2-cyano-3-amino-3-phenylancryic acetate composite usage and has apparent
Synergistic effect.
In conclusion the present invention contains the bactericidal composition of oxazole and 2-cyano-3-amino-3-phenylancryic acetate, to watermelon blight, cucumber ash
Mildew, leaf muld of tomato and wheat scab have preferable control effect, and it is safe to Target crops.Oxazole：Cyanogen
Alkene bacterium ester=90:1—1:There is synergistic effect to above-mentioned listed plant disease in 90 ranges, wherein most preferred compound proportion
It is 20:1—1:20.Complex preparation not only increases preventive effect, and expands fungicidal spectrum, widens use scope, reduces cost, right
Multiple diseases play the role of that a medicine is simultaneous to be controlled, and mitigate manpower and materials, improve productivity effect.So the invention of this complex preparation with
It promotes and disease control and crop yield raising is had a very important significance.
