example 1

[0026] Bioassay Example 1: Indoor Toxicity Determination of Dikrysstrobin Combined with Fluazinam or Fluazinamide or Benthiopyrad against P. infestans P. infestans

[0027] Test object: Potato infestation fungus (Phytophthora infestans) collected from the field

[0028] Test method: refer to the mycelium growth rate method in "Agricultural Industry Standard NY / T1156.2-2006 of the People's Republic of China". Cultivate P. infestans infestans with PDA medium. When the colonies just cover the petri dish, use a puncher with an inner diameter of 7 mm to punch holes from the edge, and the punched mycelium blocks are used as inoculum. Take 5 mL of the prepared drug solution and mix them with quantitative 75 mL of sterilized medium to make 4 drug-containing plates, and use the same amount of sterile water mixed with the medium as a control. The mycelium block was placed upside down and placed in the center of the plate, and then placed in a 28°C incubator for cultivation. After 7 da...

Abstract

The invention relates to a sterilization compound containing ZJ0712. The effective components comprise ZJ0712 (A) and any one (B) selected from fluazinam, fluopicolide and benthiavalicarb-isopropyl, 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 5-80 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 downy mildew and epidemic 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 dikrysstrobin and fluazinam or fluazinamide or benthiazil, and belongs to the field of agricultural fungicides. Background technique [0002] Downy mildew is one of the most important diseases in vegetable production. Downy mildew can occur at all stages from seedlings to harvest, and the adult plants suffer the most. It mainly damages the leaves and develops from the base to the upper leaves. In the early stage of the disease, light yellow sub-circular to polygonal lesions are formed on the leaves. When the air is humid, a frosty mold layer is formed on the back of the leaves, and sometimes it can spread to the leaves. In the later stage, the disease spots are withered and contiguous, and they are yellowish brown. In severe cases, all the outer leaves are withered and yellow and die. Field planting is too dense, watering too early after plant...
