Embodiment 1

[0026] Biological Assay Example 1: Indoor Toxicity Determination of Dikrysstrobin and Spiroxamid or Oxaflucondone on Wheat Powdery Mildew Bacteria

[0027] Test object: Wheat powdery mildew (collected from the field, cultured and stored in vivo)

[0028] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Select potted wheat seedlings at the 3-4 leaf stage with consistent growth potential, and select 5 pots for each treatment, numbered for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. For the test treatments, see Table 1, Table 2, and Table 3, and 5 concentration gradients were set for each drug. After 24 hours, the inoculum concentration was 3 × 10 5 spores / mL of wheat powdery mildew conidia suspension. Wheat seedlings sprayed with the same amount of water were used as blank control. After inoculation, the wheat seedlings were cultured in the greenhouse. After 8 days, according to the inci...

Embodiment 2

[0056] Example 2: 10% dikestrobin·oxafetocin suspension concentrate

[0057] Dikestrobin 5%, oxaflucone 5%, sodium methylnaphthalene sulfonate formaldehyde condensate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, polyvinyl alcohol (thickening agent) agent) 2%, xanthan gum (thickener) 1%, sodium chloride (antifreeze) 5%, and water to make up to 100%.

Embodiment 3

[0058] Example 3: 20.2% dikestrobin · spirulina suspension concentrate

[0059] Dikestrobin 20%, spirulina 0.2%, sodium methylnaphthalene sulfonate formaldehyde condensate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, xanthan gum (thickening agent) agent) 2%, bentonite (thickener) 1%, glycerin (antifreeze) 5%, and water to make up to 100%.

Abstract

The invention relates to a sterilization compound containing ZJ0712. The effective components comprise ZJ0712 (A) and any one (B) selected from spiroxamine and famoxadone, wherein the weight ratio of A to B is 100:1 to 1:100, and the weight percentage of the active component in the compound is 10-80 percent. The compound can be prepared into any preparation allowable in agriculture, and better preparation forms include suspending agent, wettable powder, water dispersible granules and the like. The sterilization compound is suitable for farmlands, orchards and the like and is used for preventing and treating multiple plant diseases of powdery mildew and rust diseases of crops such as corns, vegetables, fruit trees, flowers and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing dikestrobin and spiroxamid or oxaconazole, and belongs to the field of agricultural bactericides. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. Powdery mildew is widespread all over the world, especially in dicotyledonous plants. The main powdery mildews in China include cereal powdery mildew caused by Ery-siphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea; Grape powdery mildew caused by Uncinula necator; powdery mildew of more than 80 kinds of trees such as mulberry, pear, persimmon, walnut, chestnut, litchi and papaya caused by Phyllactinia corylea; Powdery mildew of Rosa flowers caused by Sphaerotheca pannosa. [0003] When the powdery mildew first occurs, the leaves produce small yellow spots, and then expand and develop into...
