[0038] Indoor Toxicity Determination of Dicyananthraquinone Compounded with Flueconazole, Flusilazole, Silfluazole, Fluquinazole and Tetrafluconazole against Apple Tree Rot Disease

[0039] Subject: Apple tree rot

[0040] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006". First, set 5 different concentration gradients for the single agent and each mixed agent (on the basis of the preliminary experimental results, according to different drug combinations and ratios, the concentration gradient settings are also different, and the bacteriostatic rate is between 5% and 90%. % within the range set according to the proportional series). Cool the melted PDA medium to 60-70°C, add quantitative medicine according to the designed amount to make toxic medium containing different doses, repeat 3 times, after it is fully cooled, inoculate apples with a diameter of 0.5cm Rotten pathogenic bacteria slices were cultured in an incubator (tempe...

[0059] Test object: rice blast fungus collected from the field

[0060] 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, make a suspension of 1×105 spores / mL, spray evenly on the test rice seedlings, cover Put on black plastic bags to keep moisture and cultivate for 24h. 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 sp...

[0079] 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 is just full of the petri dish, a puncher with an inner diameter of 5 mm is punched 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 agent. Finally, the mycelium block was placed upside down and connected to the cen...

Abstract

The invention relates to a pesticide composition containing dithianon and a triazole bactericide. The effective components of the pesticide composition comprises complexed components of dithianon (A) and a triazole bactericide (B), wherein the triazole bactericide (B) is any one selected from epoxiconazole, flusilazole, simeconazole, fluquinconazole, and tertraconazole. The weight ratio of dithianon (A) to the triazole bactericide (B) is 1:50-50:1. The total weight of the dithianon (A) and the triazole bactericide (B) accounts for 5-80% of the total weight of the pesticide. The pesticide has a substantial synergetic effect, and is mainly used for controlling anthracnose, altermaria leaf spot, scab, leaf spot, downy mildew, canker, rice blast or sheath blight, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to a pesticide composition, in particular to a pesticide composition containing dicyanoanthraquinone and triazole fungicides. Background technique [0002] Dicyanoanthraquinone (dithianon) is a fungicide developed by BASF Europe. The pure product is a dark brown crystalline solid. Molecular formula is C 14 h 4 N 2 o 2 S 2 , the chemical name is: 2,3-dicyano-1,4-dithioanthraquinone, and its structural formula is as follows: [0003] [0004] Dicyanoanthraquinone has multiple mechanisms of action. Inhibits a series of fungal enzymes by reacting with sulfur-containing groups and interfering with cellular respiration, leading to disease death. While having good protective activity, it also has certain therapeutic activity. Suitable crops for fruit trees include pome and stone fruits such as apples, pears, peaches, apricots, cherries, citrus, coffee, grapes, strawb...
