Embodiment 1

[0021] Example 1 Extraction method of plant tissue extract A.

[0022] The extraction method of plant tissue extract A is as follows: 60 parts of garlic bulbs, 30 parts of iris rhizomes, 30 parts of hibiscus leaves, 80 parts of whole thyme grass, mash them with a tissue masher and mix them together, add 10 parts of sec-butyl acetate 10 parts, 10 parts of methyl oleate, 80 parts of deionized water, after stirring with a mixer for 30 minutes, the mixed liquid was placed in a centrifuge at 6000 rpm for 30 minutes, and the supernatant was taken to obtain the plant Tissue extract A; the garlic bulbs, iris rhizomes, hibiscus leaves, and thyme whole grass are all fresh plant tissues; the fresh plant tissues refer to those with a water loss rate of less than 5% since the plant tissues leave their growth environment plant tissue.

Embodiment 2

[0023] Example 2 The preparation method of the fungicidal composition for preventing and treating watermelon anthracnose.

[0024] Take several parts of plant tissue extract A and several parts of propaneamidine prepared in Example 1, mix plant tissue extract A with propaneamidine, put them in a container and cut them with a shearing machine at 8000 rpm for 30 minutes, and then prepare Obtain the bactericidal composition.

[0025] The fungicidal composition was prepared by using A and propaneamidine prepared by the method described in Example 2 of Table 1 in different mixing ratios.

Embodiment 3

[0028] Example 3 Determination of the indoor activity of plant tissue extracts against Glosporum anthracnose.

[0029]

[0030] Table 2 The results of indoor activity determination of plant tissue extract A on colletotrichum gloeosporioides (inhibition of mycelial growth of pathogenic fungi - plate method, referring to NY / T 1156.2-2006, investigation 7 days after inoculation).

Abstract

The invention discloses a sterilization composition used for preventing and controlling watermelon anthracnose. The composition comprises plant tissue extract A and propamidine, and a mass part ratio of the plant tissue extract A to the propamidine is 1:(1-6). The plant tissue extract A is extracted from garlic bulbs, iris rhizomes, Hibiscus syriacus L. leaves and a thyme whole herb mixture, and the plant tissue extract A and the propamidine are mixed to realize synergistic effects on Colletotrichum gloeosporioides. The composition is suitable for preventing the watermelon anthracnose .

Description

technical field [0001] The invention belongs to the field of combinations of botanical pesticides and chemical pesticides and their applications. The invention relates to a fungicidal composition for preventing and treating watermelon anthracnose. Background technique [0002] Garlic bulbs, garlic, Latin scientific name Allium sativum, belong to Liliaceae Allium, with bulbs used as medicine; garlic bulbs are oblate or short conical, with off-white or light brown membranous scales on the outside, scale leaves are peeled off, and there are 6 to 10 garlic cloves, which grow in whorls around the flower stem. The base of the stem is disc-shaped and has many fibrous roots. Each garlic clove is covered with a film. When the film is peeled off, you can see white, plump and juicy scales with a strong garlic smell. Spicy. [0003] Iris, Latin scientific name Iris tectorum, also known as roof iris (Chinese Journal of Botany), blue butterfly (Guangzhou), purple butterfly, flat bamboo ...
