Embodiment 1

[0018] Biological Assay Example 1: Indoor Toxicity Determination Test of Bixafen and Metrastrobin Compounded to Cucumber Powdery Mildew Bacteria

[0019] Test object: Cucumber powdery mildew (Sphaerotheca fuliginea)

[0020] experiment method:

[0021] Measured by the pot cutting method. Select susceptible cucumber varieties for potting, and wait for the seedlings to grow to the 2-3 leaf stage for later use. The original drug of bixafen and the original drug of metrastrobin were respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. 4 pots per treatment, 10 plants per pot, repeated 4 times, evenly spray 10ml of the medicinal solution on the cucumber seedlings until they are all wet, wait for the medicinal liquid to dry naturally for later use, and set only solvent and surfactant without effective The treatment of components was used as blank control. 24 hours after the chemical treatment, the fresh spores o...

Embodiment 2

[0030] Biological Assay Example 2: Indoor Toxicity Determination Test of Bixafen and Metrastrobin Compounded on Wheat Leaf Rust

[0031] Test object: Puccinia recondita of wheat

[0032] experiment method:

[0033] Measured by the pot cutting method. Select the susceptible wheat varieties for potting, and wait for the seedlings to grow to the 2-3-leaf stage for later use. The original drug of bixafen and the original drug of metrastrobin were respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. 4 pots per treatment, 10 plants per pot, repeated 4 times, evenly spray 10ml of the liquid medicine on the wheat seedlings until they are all wet, and wait for the liquid to dry naturally for later use, and set only solvent and surfactant without effective The treatment of components was used as blank control. 24 hours after the chemical treatment, the fresh spores of leaf rust fungus produced on the diseased wheat...

Embodiment 1

[0039] Formulation example 1: 61% bixafen-nifestrobin suspoemulsion (bixafen: medistrobin = 1:60)

[0040] Made according to the conventional process, wherein bixafen 1%, metrastrobin 60%, trimethylbenzene (solvent) 10%, sodium dibutylbenzene sulfonate (wetting agent) 2%, agricultural milk 1600 (emulsifying agent) 5%, polydimethylsiloxane emulsion (defoamer) 0.4%, ethylene glycol (antifreeze) 2%, xanthan gum (thickener) 2%, deionized water to make up to 100%.

Abstract

The invention discloses a bactericidal composition containing bixafen, and applications thereof. The effective ingredients of the bactericidal composition are bixafen and meptyldinocap; the mass ratio of bixafen to meptyldinocap is controlled to be 1:60-60-1. The bactericidal composition can be used for preventing and treating a plurality of crop diseases, is especially suitable to be used for preventing and treating powdery mildew and rust disease of vegetables, fruit trees, and cereal crops, is low in using amount, is obvious in synergistic effect, and is safe.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a bactericidal composition containing bixafen and its application for preventing and controlling crop diseases, and belongs to the technical field of pesticides. Background technique [0002] Powdery mildew and rust are widespread worldwide diseases caused by powdery mildew and rust fungus respectively. [0003] In production, chemical pesticides are mainly used to control powdery mildew and rust. At present, it mainly relies on benzimidazoles, hydroxypyrimidines, phenoxyquinolines, triazoles and methoxyacrylate fungicides. These agents have produced varying degrees of resistance due to long-term use, and the control effect has decreased. In addition, triazole agents can inhibit the growth of crops when used in large doses, and easily cause phytotoxicity. Therefore, it is urgent to research and develop new effective control agents.
