Embodiment 1

[0029] The biological control method of tomato leaf mold is to take commercially available edible garlic bulbs, peel them, mash them and grind them until the particle size does not exceed 0.5mm, add tap water to fully stir according to the ratio of 60g of garlic to 1L of water, and prepare on-site The garlic control liquid with a mass concentration of 60g / L is used now with the prepared garlic control liquid, and the diseased plants are evenly sprayed, especially the back and leaf surface of the leaves; after that, the tomato plants are evenly sprayed with the garlic control liquid once every 7 days. Can significantly prevent and treat tomato leaf mold.

Embodiment 2

[0031] The biological control method of tomato leaf mold is to take commercially available edible garlic bulbs, peel them, mash them and grind them until the particle size does not exceed 0.5mm, add tap water to fully stir according to the ratio of 100g garlic to 1L water, and prepare on-site The mass concentration is 100g / L garlic control liquid, the garlic control liquid that prepares is mixed and used now, evenly sprays diseased plants, especially leaf back and leaf surface; Spray tomato plants evenly with garlic control liquid every 8 days afterwards Can significantly prevent and treat tomato leaf mold.

Embodiment 3

[0033] The biological control method of tomato leaf mold is to take commercially available edible garlic bulbs, peel them, mash them and grind them until the particle size does not exceed 0.5mm, add tap water to fully stir according to the ratio of 150g garlic to 1L water, and prepare on-site Mass concentration is the garlic control liquid of 150g / L, the garlic control liquid that prepares is prepared and used now, sprays diseased plants evenly, especially leaf back and leaf surface; Can significantly prevent and treat tomato leaf mold.

Abstract

The invention discloses a method for biologically preventing and controlling leaf mold of tomatoes. The method comprises the following steps of: grinding peeled garlic bulbs; adding water into the ground product in a ratio of 60 to 200 grams of the ground product to 1 L of water to prepare garlic control liquid; and uniformly spraying the garlic control liquid onto tomato plants once every 7 to 10 days. When the mass concentration of the garlic control liquid is 80 mg / mL, the growth of hyphae of leaf mold is fully suppressed and a suppression ratio is up to 100 percent. High-concentration garlic control liquid can fully suppress the growth of the hyphae of leaf mold of tomatoes and spore germination and does not affect the growth of tomatoes. The method sprays the garlic bulb water control liquid onto disease plants, can remarkably prevent and cure the leaf mold of tomatoes, is safe and nontoxic to tomato products and the growth of plants and is simple to operate and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of vegetable disease prevention and control, in particular to a biological control method for tomato leaf mold. Background technique [0002] Tomato is one of the most important vegetable crops in my country, with a total annual planting area of ​​over 8,395,100 hectares. Leaf mold is one of the important diseases in tomato production, especially under the conditions of low temperature and high humidity in protected areas, it takes about 10-15 days for tomato leaf mold to develop from the initial stage to the peak stage, and the diseased leaf rate in general fields will reach 30 % to 40%, and the rate of diseased leaves in seriously diseased fields is as high as 90%, which will cause plant chlorosis, dry leaves, and thin fruits. The epidemic speed of the disease is fast, and it can break out into disasters in a short period of time, and the output loss is generally about 20% to 30%, and it can reach more th...
