Problems solved by technology

[0004] The main prevention and treatment agent of this disease is carbendazim, although it has played a certain effect of disease prevention and control, there are many shortcomings: 1. Due to long-term single use, certain resistance has been produced
II. The amount of medication is large, the phenomenon of drug waste and environmental pollution is serious
III. Spraying carbendazim can easily induce rust

Embodiment 1

[0014] The medicament comprises diniconazole, carbendazim and high-lipid film evenly mixed, and the ratio of diniconazole, carbendazim and high-lipid film is 1:1:1.2 by weight, and the medicament is made into powder. Spray the above-mentioned agents at the early stage of the onset of peanut black spot. The medicament and water are diluted according to the weight ratio of 1:600 ​​and then sprayed. During the control process, the medicament is sprayed twice with an interval of 10 days.

[0015] Adopt medicament of the present invention to contrast other medicaments to prevent and treat peanut black spot effect:

[0016]

[0017] After 2 years and 8 demonstration base points for the prevention and treatment of peanut black spot, the control effect of the present invention is significantly higher than that of the control treatment of carbendazim, and the average control effect on peanut black spot is as high as 78.3%. Effectiveness is only 44.3%, obviously lower than the prese...

Embodiment 2

[0021] The medicament comprises diniconazole, carbendazim and high-lipid film evenly mixed, and the ratio of diniconazole, carbendazim and high-lipid film is 1:1:1 by weight, and the medicament is made into powder. Spray the above-mentioned agents at the early stage of the onset of peanut black spot. The medicament and water are diluted according to the weight ratio of 1:550 and then sprayed. During the control process, the medicament is sprayed twice with an interval of 12 days.

Embodiment 3

[0023] The medicament comprises diniconazole, carbendazim and high-lipid film evenly mixed, and the ratio of diniconazole, carbendazim and high-lipid film is 1:1:2 by weight, and the medicament is made into powder. Spray the above-mentioned agents at the early stage of the onset of peanut black spot. The agent and water are diluted according to the weight ratio of 1:600 ​​and then sprayed. During the control process, the pesticide was sprayed twice, with an interval of 14 days.

Abstract

The invention relates to an agriculture agent, in particular to a mixed chemical for controlling cercospora black spot of peanut and a control method of cercospora black spot of peanut. The chemical for controlling the cercospora black spot of peanut of the invention comprises diniconazole, carbendazol and palmityl alcohol which are mixed evenly in proportion by weight of 1:1:1-2. Proven by testing, the combination bactericide of the invention has stable chemical property and obvious synergism, and presents obvious synergism and complementary effects on the controlled object.

Description

technical field [0001] The invention relates to a pesticide, in particular to a compound agent for preventing and controlling peanut black spot and a method for preventing and treating peanut black spot. Background technique [0002] Peanut black spot, also known as late spot, commonly known as "black jaundice" and "black astringent" disease, is the most common leaf fungal disease in peanut production areas at home and abroad. The peak of incidence mostly occurs in the middle and late stages of peanut growth, so it is called "late spot" disease. It often causes a large number of leaves to fall on the plant, resulting in hindered pod development and a sharp drop in yield. [0003] The lesions of peanut black spot are dark brown, and there is usually no yellow halo around them, or there is a narrow, inconspicuous pale yellow halo. On the lesion on the back of the leaf, there are usually many black dots (spores) in the shape of concentric rings, and there is a layer of dark b...
