Embodiment 1
[0020] The control effect of embodiment 1 chitosan oligosaccharide composition to rice sheath blight
[0021] A single compound or composition is dissolved in an organic solvent to prepare a 1000 mg / L mother solution. According to the preliminary test of biological activity, a certain amount of the above mother solution was diluted with 0.1% Tween 80 to prepare the required concentration. During the measurement, first spray the medicinal liquid on potted rice plants with the same growth period and growth, after 7 days, spray the mycelia suspension quantitatively for each treatment, after moisturizing for 24 hours, place it in a greenhouse for cultivation, and measure the leaves of the plants after a certain period of time. percentage of infestation. Convert percentages to efficacy using Abbot's formula.

Embodiment 2
[0029] The control effect of embodiment 2 chitosan oligosaccharide composition to cucumber downy mildew
[0030] A single compound or composition is dissolved in an organic solvent to prepare a 1000 mg / L mother solution. According to the preliminary test of biological activity, a certain amount of the above mother solution was diluted with 0.1% Tween 80 to prepare the required concentration. During the test, the cucumber plants were basically at the 4-leaf stage, and the incidence of downy mildew was investigated before the first medicine. A potted test of cucumber downy mildew was carried out with the chitosan oligosaccharide composition, and a corresponding single agent and blank control were set up, and a hand-held sprayer was used for conventional constant spraying, and 10 plants were sprayed with each agent, and sprayed again 7-10 days after spraying once. 10-14 days after the second spraying, investigate all the leaves of each plant, record the total number of leaves an...
Embodiment 3
[0045] Embodiment 3 chitosan oligosaccharide composition is to wheat smut field test
[0046] Carried out wheat smut field test with composition, and set up corresponding single agent and blank control, each agent is set plot 20m 2 . Seed dressing with 20-30 grams (active ingredients) per 100 kilograms of seeds. In the milky stage or mature stage of wheat, each plot is sampled at 5 points diagonally, and each point takes 0.5m 2 Investigate the total number of plants and the number of smut diseased plants, and calculate the rate of diseased plants.
