Embodiment 1

[0037] WP 1: 0.1% brassinolide wettable powder

[0038] 0.1wt% brassinolide, 1wt% sodium lignosulfonate, 7wt% sodium dodecylbenzenesulfonate, and 100wt% white carbon black.

[0039] Preparation method: Calculate, weigh and mix according to the mass percentage of the active ingredient, dispersant, wetting agent and carrier, and then pulverize to 300-400 mesh with a jet mill to obtain a wettable powder.

[0040] Application method: dilute 200 times with water, spray once on the leaves 25 days before the garlic sprouts are harvested, and spray the second time 15 days before the garlic sprouts are harvested. The control group was treated with water spray. Three parallels were performed for each treatment.

Embodiment 2

[0042] Wettable powder 1: 10% sodium nitrophenolate wettable powder

[0043] 10wt% sodium nitrophenolate, 1wt% sodium lignosulfonate, 7wt% sodium dodecylbenzenesulfonate, and 100wt% white carbon black.

[0044] The preparation method is the same as in Example 1.

[0045] Application method: dilute 200 times with water, spray once on the leaves 20 days before harvesting garlic sprouts, and spray for the second time 10 days before harvesting garlic sprouts. The control group was treated with water spray. Three parallels were performed for each treatment.

Embodiment 3

[0047] WP 3: 10% Sodium Nitroprusside WP

[0048] Sodium nitroprusside 10wt%, sodium lignosulfonate 1wt%, sodium dodecylbenzene sulfonate 7wt%, white carbon black make up 100wt%.

[0049] The preparation method is the same as in Example 1.

[0050] Application method: dilute 200 times with water, spray once on leaves 28 days before harvesting garlic sprouts, and spray for the second time 10 days before harvesting garlic sprouts. The control group was treated with water spray. Three parallels were performed for each treatment.

Abstract

The invention discloses a composition for preventing and treating garlic sprout yellow spot and an application method thereof. The composition uses brassinolide, sodium nitrophenolate, and sodium nitroprusside as active ingredients, and then adds certain additives and fillers to make various preparations such as wettable powder, effervescent tablet, or water-dispersible granule. , After diluting with water to a certain number of times, spray it before garlic sprouts are harvested. The beneficial effect of the invention is that the composition can effectively control the yellow spot disease of garlic sprouts, has simple preparation process, low cost, good effect, high biological safety and can promote yield increase of garlic sprouts.

Description

technical field [0001] The invention belongs to the field of crop disease prevention and control, and relates to a composition for preventing and treating garlic stalk yellow spot disease and an application thereof. Background technique [0002] Garlic scape is the young flower stem of garlic, which is rich in nutrition and has outstanding functions, and is deeply loved by consumers. Garlic sprouts can be stored in batches and for a long time through low temperature, air conditioning and other measures to achieve annual supply. However, garlic sprouts will be threatened by various diseases before and after harvest, and the main disease before harvest is garlic sprout yellow spot. [0003] Garlic stalk yellow spot refers to the yellow spots that appear on the stalks and buds of garlic stalks, which are the size of sesame seeds in the early stage, scattered in spots, and will connect into pieces in severe cases. After the garlic sprouts with macular disease are stored in col...
