Example 3
Grape powdery mildew control effect experiment:
the test grape seedlings are 40 in total, and are divided into A, B, C groups and D groups, wherein each group comprises 10 grape seedlings. Fresh grape powdery mildew diseased leaves are taken, distilled water is dipped by a brush pen to wash spores on the back of the diseased leaves, and spore suspension is prepared. Then the spore suspension is evenly sprayed on four groups of grape seedlings by using an inoculation sprayer to complete inoculation.
After inoculation, four groups of grape seedlings are cultured in a climatic chamber (the temperature is 20 ℃, the humidity is 68-72 percent, and the illumination time is 12 h/day). 2 days after inoculation, group a grape seedlings were sprayed with the composition prepared in example 1 (diluted 1500 times with distilled water); spraying the composition prepared in the comparative example 1 (diluted by 1500 times with distilled water) on grape seedlings in the group B; spraying the composition prepared in the comparative example 2 (diluted by 1500 times with distilled water) on grape seedlings in the group C; and D, spraying clear water (blank control) on the grape seedlings. After the culture is continued for 2 weeks, the powdery mildew morbidity of grape seedlings in each group is counted according to the following standard, and the control effect of the composition on the powdery mildew is calculated.
The grading criteria of leaf disease are as follows:
grade 0, no disease;
grade 1, the area of the scab accounts for less than 5% of the area of the whole leaf, the scab is fine, and the scab is difficult to distinguish;
grade 3, the range of the scab occupies 5 to 10 percent of the whole fruit area, and the scab are easy to distinguish;
grade 5, the range of the scab occupies 11 to 20 percent of the whole fruit area, and the scab is large;
7-grade, the range of the scab occupies 21-40% of the whole fruit area, and the scab is large;
grade 9, the range of scab is more than 40% of the whole fruit area, and the scab is large and obvious.
The statistical results are shown in table 1:
TABLE 1 statistical results of leaf disease of grape powdery mildew
| Group of | Level 0 | Level 1 | Grade 3 | Grade 5 | Stage 7 | Grade 9 | Total number of blades |
| A | 62 | 32 | 3 | 0 | 0 | 0 | 97 |
| B | 36 | 38 | 15 | 9 | 5 | 1 | 104 |
| C | 33 | 25 | 22 | 7 | 9 | 0 | 96 |
| D | 12 | 25 | 31 | 27 | 8 | 5 | 108 |
