As can be seen from Table 1, the samples of the other two examples were found to be good except that the sample of example 2 was slightly cloudy and crystallized upon cold storage.
TABLE 23 description of the Properties of the Water-dispersible granules
As can be seen from Table 2, the performance indexes of example 4 are relatively better, the suspension percentage is higher, the dispersibility is better, and the lasting foamability is smaller.
TABLE 32 characterization of the powders
| Suspension Rate (%) | Wettability(s) | Permanent foaming Property 1mim/ml | |
| Example 7 | 85.3 | 13 | 7 |
| Example 8 | 79.2 | 13 | 8 |
As can be seen from Table 3, example 7 has a higher suspension percentage and a lower difference between wettability and permanent foaming than example 8, and example 7 is superior to example 8.
Product effect experiment:
1) field efficacy test of soybean root rot:
the invention adopts 6 treatments in total, and the water agent containing ningnanmycin and sugar alcohol zinc prepared by the invention (example 1 and example 3); the water dispersible granule (example 4) prepared by the invention contains ningnanmycin and zinc saccharate; the invention made powder containing ningnanmycin, sugar alcohol zinc (example 7); control agent 8% ningnanmycin aqueous solution (de qiang bio ltd) and clear water control.
The test site is a cluster village in the tender river town of the county of the Yangjiang province of Heilongjiang province. Soybeans were sown in 2019, 4 months and 23 days. The water dispersible granule and the wettable powder coat and mix seeds according to the designed dosage before sowing, and are dried for standby. The water agent is applied by irrigation. No fungicide, insecticide was applied before and during the test, and the test was repeated 3 times per treatment, with cells randomly arranged, and with an area of 20m2 per cell. The concrete results are as follows:
the investigation method comprises the following steps: investigating at 30d and 60d after seedling, investigating the disease condition of the root part according to the classification standard of soybean root rot, and finally calculating the control effect of each treatment.
Grading standard of soybean root rot: grade 0, the base of the seedling stem and the main root have no disease spots; grade 1, disease spots are arranged on the base part of the stem and the main root, and the area of the disease spots accounts for less than 1/4 of the total area of the stem and the main root; grade 2, the lesion area on the stem and the main root accounts for about 1/4-1/2 of the total area of the stem and the main root; grade 3, the lesion spots account for more than 1/2 of the area of the stem and the main root; 4, the stalk winding phenomenon is formed by connecting the base of the stalk and the lesion spots on the main root, but the root system is not necrotic; grade 5, withering or withering of the overground part.
Disease index ∑ [ disease plant number of each stage × corresponding stage)/(total investigated plant number × 5) ] × 100
The prevention and treatment effect (%) is [1- (disease index before drug administration in blank control area x disease index after drug administration in drug treatment area)/(disease index after blank drug administration x disease index in drug treatment area) ] × 100
TABLE 4 pharmacological results of Soybean root rot
TABLE 5 Soybean yield
| Drug treatment | Dosage (kg/hm)2) | Theoretical yield | Actual yield |
| Example 1 | 72 | 223 | 231 |
| Example 3 | 144 | 231 | 242 |
| Example 4 | 72 | 219 | 225 |
| Example 7 | 720 | 221 | 229 |
| 8% ningnanmycin water solution | 90 | 213 | 219 |
| Blank control (clear water)) | —— | 203 | 196 |
According to the experimental data in tables 4 and 5, the control effect of the product developed by the embodiment of the invention is obviously higher than that of a control medicament and a blank control, compared with the three dosage forms, the control effect and the yield increasing effect of the aqueous agent are better than those of powder and water dispersible granules, and compared with the water dispersible granules, the powder has better control effect and yield increasing effect. When the ningnanmycin content is equal, the higher the sugar alcohol zinc content is, the better the prevention and treatment effect and the yield increase effect are.
2) Apple powdery mildew drug effect test:
the invention adopts 6 treatments in total, and the water agent containing ningnanmycin and sugar alcohol zinc prepared by the invention (example 1 and example 3); the water dispersible granule (example 4) prepared by the invention contains ningnanmycin and zinc saccharate; the invention made powder containing ningnanmycin, sugar alcohol zinc (example 7); control agent 8% ningnanmycin aqueous solution (de qiang bio ltd) and clear water control.
