Embodiment 1

[0042] Example 1 Indoor combined toxicity test

[0043] (1) Preparation of PDA medium: Peel and cut 200g potatoes, add 1000mL distilled water, and boil for 30min. Filter with gauze and add distilled water to 1000mL. Add 20g glucose and 17g agar, heat to melt, pack, autoclave for 25min, and set aside.

[0044] (2) Cultivation of pathogenic fungi: Use an inoculating needle to pick a small amount of pathogenic mycelium on the PDA medium and place it in a constant temperature incubator at 25°C for 2-4 days. After the hypha grows well, it will be used.

[0045] (3) Determination method: The mycelial growth rate method (the size of the colony diameter within a certain period of time) is used to determine the antibacterial activity of the compound. Accurately weigh 5 mg of the test target in a centrifuge tube, first dissolve it with an appropriate amount of acetone, and then add a calculated amount of an aqueous solution containing 1% Tween 20 emulsifier, and dilute it into a 1000 mg / L so...

Abstract

The invention relates to the technical field of pesticide fungicides, in particular to a chemical bactericide pesticide capable of preventing blueberry fruit rot. The chemical bactericide pesticide isprepared from the following raw materials in percentage by weight: 50.0% of pyraclostrobin and DX110512(N-(5-trifluoromethyl-3,4-thiadiazole-2-yl)-2-fluorobenzamide, 2.2% of uniconazole, 5.0-15.0% ofauxiliaries, and 32.8-42.8% of a filler carrier. The bactericidal composition adopts three medicaments as main ingredients, and is matched with auxiliaries and the filler carrier to achieve the effects of having compensatory advantages and supplementing each other. The preparation is simple in process, the added raw materials are completely converted into products, the yield is high, no three wastes are generated, and the control effect on blueberry fruit rot is effectively improved.

Description

Technical field [0001] The present invention belongs to the field of pesticides. The technical proposal relates to the preparation and application of a chemical pesticide for preventing and treating blueberry fruit rot, increasing blueberry yield and improving blueberry quality, and specifically relates to pyraclostrobin and an ortho-substituted benzoyl compound and Preparation of compound pesticide of plant growth regulator Uniconazole and its application in preventing and controlling blueberry fruit rot. Background technique [0002] The English name of blueberry is Blueberry, which means blue berry, belonging to the rhododendron family and the lingonberry. Originated in North America, a perennial shrub with small berry fruit trees. Because the fruit is blue, it is called blueberry. One is low shrubs, short-footed wild, small particles, rich in anthocyanins; the second is artificially cultivated blueberries, which can grow to 240cm high, with larger fruits and full flesh, whi...
