[0026] Indoor Toxicity Determination of Prothioconazole and Dikrysstrobin, Syringstrobin, Enoxastrobin or Pyclostrobin on Rice Magnaporthe grisea

[0027] Test object: rice blast fungus collected from the field

[0028] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", pot method. Select rice seedlings at the three-leaf stage with consistent growth potential, 2 seedlings per pot, and 5 pots of rice seedlings for each treatment. Cultivate Magnaporthe grisea on tomato oat agar medium, wash the spores with sterile water after spore production, and make 1×10 5 spores / mL suspension, sprayed evenly on the rice seedlings to be tested, and covered with a black plastic bag to moisturize and cultivate for 24 hours after inoculation. 24 hours after inoculation, carry out medicament treatment, set 5 concentration gradients for each medicament, and spray at 50PSI pressure with a Potter spray tower, about 5ml per pot. After spraying, the r...

[0049] Indoor Toxicity Determination of Prothioconazole and Dikrysstrobin, Syringstrobin, Enoxastrobin or Pyclostrobin on Rice Sheath Blight

[0050] Test object: Rice sheath blight fungus collected from the field

[0051] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", broad bean detached leaf method. Rice sheath blight fungus is cultivated with PDA medium, and when the bacterial colony just covers the petri dish, a puncher with an inner diameter of 5 mm is used to punch holes from the edge, and the resulting mycelium block is used as an inoculum. Select broad bean leaves with the same leaf position, 10 leaves for each treatment, soak in the prepared medicinal solution for 10 minutes, take it out to dry, put it in a petri dish covered with moisturizing paper, and set 5 concentration gradients for each medicinal solution. Finally, the mycelium block was placed upside down in the center of the leaves, and cultured in a constan...

[0067] Indoor Toxicity Determination of Prothioconazole and Dikrysstrobin, Syringstrobin, Enoxastrobin or Pyclostrobin on Rice Aspergillus oryzae

[0068] Test object: rice smut fungus collected from the field

[0069] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", mycelium growth rate method. The rice smut fungus is cultivated with PDA medium. When the bacterial colony is just full of the petri dish, a puncher with an inner diameter of 7 mm is used to punch holes from the edge, and the resulting mycelium block is used as an inoculum. Take 5ml of prepared medicine solution and 75ml of sterilized culture medium and mix evenly to make 4 medicine-containing liquid plates, and mix equal amount of sterile water and culture medium as a control. The mycelium block was placed upside down and placed in the center of the plate, and cultured in a 28°C incubator. After 7 days, the colony diameter was measured by the cross method, and t...

Abstract

The invention discloses a pesticide composition containing prothioconazole and methoxyl acrylic ester bactericides. The pesticide composition consists of an active ingredient, auxiliaries and an excipient, wherein the active ingredient consists of an active component A and an active component B, the active component A is prothioconazole, and the active component B is selected from any one of benzene kresoxim-methyl, coumoxystrobin, SYP or pyraoxystrobin; and the weight ratio of the active component A to the active component B is (80:1)-(1:60). The pesticide composition is obvious in synergistic effect, the defects of the prevention and treatment of the single bactericide, namely high medicament use level, serious environment pollution and quick pathogenic bacteria generation speed can be overcome, the use level of medicaments can be reduced on the premise that the optimal control effect is guaranteed, the cost can be reduced, the damage to the environment can be reduced, and the generation of the drug resistance of germs can be delayed.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and relates to a pesticide composition, in particular to a pesticide composition containing prothioconazole and methoxyacrylate fungicides. Background technique [0002] Prothioconazole, English name Prothioconazole, is a new type of broad-spectrum triazolethione fungicide developed by Bayer, mainly used to prevent and control many diseases of cereals, wheat and legumes. Its structural formula is as follows: [0003] [0004] Prothioconazole has low toxicity, and its mechanism of action is to inhibit the demethylation at the 14-position of lanosterol or 2,4-methylenedihydrolanosterol, the precursor of sterol in fungi, that is, the demethylation inhibitor ( DMIs). Not only has good systemic activity, excellent protection, treatment and eradication activity, but also has a long lasting effect. Through a large number of field efficacy tests, the results show that prothioconazole ...
