Specific embodiment
In order that the object of the invention, technical scheme and advantage are more short and sweet, present invention specific examples below is entered
Row explanation, but the present invention is only limitted to absolutely not these examples.Described below is only the preferable embodiment of the present invention, is used only for describing
The present invention is it is impossible to be interpreted as limiting the scope of the present invention.It should be pointed out that all within the spirit and principles in the present invention
Any modification, equivalent and improvement of being made etc., should be included within the scope of the present invention.Therefore, the present invention is special
The protection domain of profit should be defined by claims.
In these embodiments, unless otherwise indicated, all percentage ratios are percentage by weight after folding hundred.
Chemical prevention information system of crop pest distribution in China is common method, and different types of pesticide active ingredient is combined, and leads to
Often show three kinds of type of action, i.e. antagonism, summation action and potentiation.
Embodiment 1：Zhongshengmycin frost mould to Fructus Cucumidis sativi with fluorine ether bacterium amide mixture virus power determination test.
Adopt field Fructus Cucumidis sativi nebulization dispenser (having water membrane to be advisable with blade surface), spray apparatus adopts hand spray
Device (liquid capacity about 2.0L), every 10 days sprays once, continuously spray 2 times.Often process and select uniform 20 blades of morbidity
As efficacy of medicine observing object, each processes 3 repetitions.
According to blank incidence, classification investigation is carried out to inoculation blade, using following stage division
0 grade：Anosis；
1 grade：Lesion area accounts for less than the 5% of full wafer leaf area；
3 grades：Lesion area accounts for the 6%～10% of full wafer leaf area；
5 grades：Lesion area accounts for the 11%～20% of full wafer leaf area；
7 grades：Lesion area accounts for the 21%～40% of full wafer leaf area；
9 grades：Lesion area accounts for more than the 40% of full wafer leaf area；
According to survey data, calculate disease index and prevention effect.
(1) disease index is calculated by formula, and result of calculation retains 2 significant digits：
In formula：
X represents disease index；
NiRepresent the disease numbers of sheets at different levels；
I represents value of series relatively；
N represents investigation total number of sheets.
(2) prevention effect is calculated by formula：
In formula：
P represents prevention effect, and unit is percentage rate (%)；
CK represents blank disease index；
PT represents chemicals treatment disease index.
Survey standard method NY/T1156.4-2006 with reference to raw, according to the co-toxicity coefficient method of Sun＆Johnson (1960)
(CTC) evaluating the potentiation of pharmacy mix, that is, CTC≤80 are antagonism, 80<CTC<120 is summation action, CTC >=
120 is potentiation.
The percentage composition of A medicament in toxicity index × 100 mixture of mixture theoretical toxicity index (TTI)=medicament A
The percentage composition of the toxicity index × 100 mixture Chinese medicine of+medicament B
Can be seen that Zhongshengmycin and fluorine ether bacterium amide portfolio ratio 1～10 from table 1, table 2：1～20 co-toxicity coefficient (CTC
Value) it is all higher than 120, illustrate that Zhongshengmycin and the combination of fluorine ether bacterium amide are notable to cucumber downy mildew potentiation.
Table 1, Zhongshengmycin, fluorine ether bacterium amide and combinations thereof are to cucumber downy mildew toxicity test result
Table 2, Zhongshengmycin, fluorine ether bacterium amide and combinations thereof are to cucumber downy mildew toxicity test result
Embodiment 2：18% Zhongshengmycin fluorine ether bacterium amide wettable powder.
12% Zhongshengmycin 25 parts of medicine of mother (effective ingredient), 98% fluorine 15.3 parts of bacterium amide active compound of ether (effective ingredient), wood
5 parts of quality sodium sulfonate (auxiliary agent), 7 parts of alkyl naphthalene sulfonic acid condensation polymer sodium salt (auxiliary agent), 5 parts of sodium lauryl sulphate (auxiliary agent), carbon
Sour 5 parts of hydrogen sodium (auxiliary agent), 10 parts of bentonite (auxiliary agent), 27.7 parts of Kaolin (auxiliary agent).Will be mixed through machinery to effective ingredient and auxiliary agent
Close and pulverize, after jet mill 2 times, you can obtain 18% Zhongshengmycin fluorine ether bacterium amide wettable powder.Wherein, middle life
Rhzomorph weight/mass percentage composition 3%；Fluorine ether bacterium amide weight/mass percentage composition 15%.
Embodiment 3：Field control effectiveness test
It is used for preventing and treating cucumber downy mildew using 18% Zhongshengmycin fluorine ether bacterium amide wettable powder, in cucumber downy mildew
Their early stage is watered spraying, and every dispenser in 5 days once, continuous dispenser is secondary.
From table 3 it can be seen that preventing and treating cucumber downy mildew, 3% Zhongshengmycin 15% fluorine ether bacterium amide wettable powder has
5 days, 10 days prevention effects 70.26～77.59%, 81.09～86.97% after effect 40～60 grams/ha of medicines of Ingredient Amount, preventing and treating
Prevent within 5 days, 10 days after effect is substantially better than single dose 15% fluorine ether bacterium amide wettable powder and 3% Zhongshengmycin wettable powder medicinal
Control effect 68.02%, 60.42 and 71.64%, 63.57%.
Table 3,3% Zhongshengmycin 21% fluorine ether bacterium amide wettable powder preventing and treating cucumber downy mildew statistical table.
