Embodiment 1

[0017] Example 1: Indoor toxicity determination of epoxiconazole, astragalus polysaccharide and their mixture on mango anthracnose

[0018] Test object: mango anthracnose, half-know fungus Anthracnose genus Calletotrichum gloesporioides

[0019] Test method: Mycelia growth rate method was adopted. Take 5ml of the prepared experimental reagent and add it to an Erlenmeyer flask containing 45ml of hot medium (PDA medium, 45-50°C). After shaking well, quickly pour it into a 90mm diameter glass petri dish, and pour each 12ml of drug-containing medium, 4 replicates for each treatment, placed horizontally, and formed a plate after cooling. Use a 5mm diameter punch to cut the fungus cake from the edge of the test bacteria that has been cultured for 5 days, and use a pick needle to connect the side with mycelium to the poisonous medium. All operations are performed aseptically on the ultra-clean workbench. After the treatment, the plates were cultured in a constant temperature steril...

[0034] Embodiment 2: 6.0% epoxiconazole · astragalus polysaccharide suspension

[0035] Formula: take by weighing epoxiconazole 5.0%, astragalus polysaccharide 1.0%, alkylnaphthyl sulfonate 2.5% (wetting agent), polycarboxylate 1.5% (dispersant), xanthan gum 0.5% (additive Thickener), ethylene glycol 1.2% (antifreeze), silicone oil 0.3% (defoamer), deionized water to 100%.

Embodiment 3

[0036] Example 3: 10% epoxiconazole·astragalus polysaccharide suspension

[0037] Formula: take by weighing epoxiconazole 5.0%, astragalus polysaccharide 2.5%, alkylnaphthyl sulfonate 2.5% (wetting agent), polycarboxylate 5% (dispersant), xanthan gum 0.5% (increase Thickener), ethylene glycol 2.5% (antifreeze), silicone oil 0.3% (defoamer), deionized water to 100%.

Abstract

The invention relates to a sterilizing composition capable of preventing and controlling anthracnose of mango. The sterilizing composition is prepared from the following effective ingredients of epoxiconazole and astragalus polysaccharides according to a weight ratio of (2 to 10) to 1. The sterilizing composition has the advantages that the synergistic effect is realized; the anthracnose of mangocan be effectively prevented and controlled; the output of the fruit is increased, and the quality is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural prevention and control, in particular to a bactericidal composition for preventing and treating mango anthracnose. Background technique [0002] Mango is one of the famous tropical fruits. Mango fruit contains sugar, protein, and crude fiber. The precursor carotene of vitamin A contained in mango is particularly high, which is rare among all fruits. Secondly, the vitamin C content is not low, and minerals, protein, fat, sugar, etc. are also its main nutrients. Mango has become one of the pillar industries of Guangxi's rural economy. [0003] Anthracnose is the main disease in the process of mango planting, which has caused serious losses to mango production. The disease mainly damages young leaves, shoots and fruits, and has a great impact on mango tree vigor, yield and quality. [0004] Epoxiconazole, common name in English: epoxiconazole, is a triazole fungicide with protection, treatment ...
