Problems solved by technology

[0014] The purpose of the present invention is to provide a kind of fungicidal composition containing prothioconazole for the above-mentioned problems of using a single active ingredient to prevent and treat crop diseases, which overcomes the large amount of medicament used in the prevention and control of a single fungicide, serious environmental pollution and pathogen resistance. Defects are produced at a high speed; the use of chemicals can be reduced while ensuring the optimal control effect, the cost can be reduced, the harm to the environment can be reduced, and it is beneficial to delay the emergence of bacterial resistance

[0029] Indoor virulence determination of rice blast fungus in a pair of prothioconazole and pyraclostrobin, picoxystrobin, kresoxim-methyl, kresoxim, fenoxystrobin and orysastrobin

[0030] Test object: Magnaporthe grisea collected from the field

[0031] Test method: refer to "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", potting method. Select rice seedlings at the three-leaf stage with the same growth potential, 2 seedlings per pot, and 5 pots for test rice seedlings for each treatment. The rice blast fungus was cultured on tomato oat agar medium, and the spores were washed with sterile water after sporulation to make 1×10 5 A spore / mL suspension was uniformly sprayed and inoculated on the tested rice seedlings. After inoculation, the seedlings were put on a black plastic bag and kept for 24 hours. After 24 hours of inoculation, the agent was treated with 5 concentration gradients for each agent, and sprayed with a Potter spray tower at a press...

[0056] Indoor virulence determination of a pair of prothioconazole and any one of pyraclostrobin, picoxystrobin, kresoxim-methyl, ketoxystrobin, fenoxystrobin and orysastrobin on rice sheath blight

[0057] Test object: Rhizoctonia solani from the field

[0058] Test method: Refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", broad bean separated leaf method. The rice sheath blight fungus was cultured with a PDA medium, and when the colony just overgrown the petri dish, punched holes from the edge with a punch with an inner diameter of 5 mm, and the punched hyphae block was used as an inoculum. Select broad bean leaves with the same leaf position, each treatment 10 slices, soak them in the prepared medicinal solution for 10 minutes, take them out to dry, and put them in a petri dish covered with moisturizing paper, and set 5 concentration gradients for each medicine. Finally, the mycelium block was placed upside down in the center of the leaf and ...

[0079] Indoor virulence determination of a combination of prothioconazole and pyraclostrobin, picoxystrobin, kresoxim-methyl, ketoxystrobin, fenoxystrobin, orysastrobin

[0080] Test object: Oryza sativa collected from the field

[0081] Test method: Refer to "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", mycelial growth rate method. The rice aspergillus oryzae was cultured with PDA medium, and when the colony had just overgrown the petri dish, a hole was punched from the edge with a punch with an inner diameter of 7 mm, and the punched hyphae block was used as an inoculum. Take 5ml of the prepared medicinal solution and 75ml of sterile medium and mix them evenly to make 4 plates containing medicinal liquid, and mix the same amount of sterile water with the medium as a control. The mycelium block was connected upside down to the center of the plate and cultured in an incubator at 28°C. After 7 days, the colony diameter was measured by the cross m...

Abstract

The invention discloses a bactericidal composition containing prothioconazole, which is composed of an effective ingredient, an auxiliary and an excipient, wherein the effective ingredient is composed of an active constituent A and an active constituent B, the active constituent A is prothioconazole, and the active constituent B is any one selected from pyraclostrobin, picoxystrobin, kresoxim-methyl, dimoxystrobin, metominostrobin or orysastrobin; the effective ingredient accounts for 1-90% of the composition in percentage by weight, and the weight ratio of the active constituent A to the active constituent B is 0: 1 to 1: 60; and the composition is prepared into one of wettable powder, water dispersible granules, a suspending agent, a micro-capsule suspending agent, granules or an aqueous emulsion. The bactericidal composition containing prothioconazole disclosed by the invention is obvious in synergistic effect, capable of overcoming the defects of high medicament dosage, serious pollution to environment and fast pathogenic bacteria resistance generation speed existing in prevention and treatment adopting a single bactericidal agent, realizing reduction for medicament dosage while ensuring the optimal prevention and treatment effect, thus reducing cost and harm to environment, and beneficial to delaying the generation of pathogenic bacteria resistance to medicine.

Description

Technical field [0001] The invention belongs to the technical field of pesticide preparations, and relates to a pesticide composition, specifically a bactericidal composition containing prothioconazole. Background technique [0002] During the entire growth process of crops, there are many threats such as diseases, insects, grasses and other pests. Among them, diseases, especially fungal diseases, are characterized by their wide variety, complex symptoms, rapid spread, serious damage, and compound occurrence. Make it more difficult to prevent, posing a huge threat to crop yield and quality. In the process of agricultural production, in order to reduce the losses caused by fungal diseases, chemical control is one of the more significant methods at present. However, due to the unscientific use of drugs such as unity, continuity, and repetition, many pathogens have been used for a long time. The drugs currently in use produce varying degrees of resistance, and it is reported that d...
