example 1

[0027] Biological Assay Example 1: Indoor Toxicity Determination of the Compound of Hemifluphos and Azoxystrobin, Kresstrobin, Pyraclostrobin, and Picoxystrobin on Rice Magnaporthe grisea

[0028] Test object: rice blast fungus collected from the field

[0029] 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,...

[0051] Biological Assay Example 2: Indoor Toxicity Determination of Tobacco Virus Disease Compounded by Hemifluphos and Azoxystrobin, Kresstrobin, Pyraclostrobin, and Picoxystrobin

[0052] Subject: Tobacco virus disease

[0053] Test method: Indoor potted tobacco susceptible plants are planted to the 4-5 leaf stage, mixed with equal volumes of virus juice with different ratios and different concentrations of medicaments for friction inoculation, 3 plants for each treatment, and 3 leaves for each plant, repeated 4 times, After 3-4 days, investigate the number of dead spots, calculate the inhibition rate, and use EC 50 The toxicity index and co-toxicity coefficient (CTC) of the drug were calculated according to Sun Yunpei's method.

[0054] The results of toxicity test (Table 5) showed that when the ratio of metamidophos and azoxystrobin was between 50:1~1:50, it had obvious synergistic effect on tobacco virus disease, especially at 20:1~1 : Between 20, the co-toxicity coeffi...

Embodiment 1

[0070] Embodiment 1: 5% toxic fluorophos. Azoxystrobin suspension concentrate

[0071]

[0072]

[0073] Mix the active ingredient, dispersant, thickener, wetting agent, antifreeze agent and water according to the proportion of the formula and mix them evenly, and get 5% poisonous phosphine after high-speed shearing. Azoxystrobin suspension.

[0074] This embodiment is applied to the prevention and treatment of rice blast. 5% Poison Fluorophos. Azoxystrobin suspension concentrate was diluted with water at 300g a.i. / ha and sprayed, and the control effect was 88.9% 10 days after application. 200g a.i. / ha of 30% hexafluorophos wettable powder and 300g a.i. / ha of 25% azoxystrobin suspending concentrate were diluted with water and sprayed. The control effects were 73.2% and 81.4% after 10 days of application. The synergistic effect of the combination of hemifluphos and azoxystrobin is obvious, and the control effect on rice blast is obviously better than that of a single ...

Abstract

The present invention discloses a sterilization composition containing Dufulin, wherein the active ingredient is prepared by compounding Dufulin A and a strobilurins sterilant B, the strobilurins sterilant B is one selected from azoxystrobin, kresoxim-methyl, pyraclostrobin, and picoxystrobin, a weight ratio of the Dufulin A to the strobilurins sterilant B is 50:1-1:50, the total weight of the Dufulin A and the strobilurins sterilant B is 5-80% of the total weight of the sterilization composition, and the sterilization composition can be prepared into a wettable powder agent, a suspending agent, water-dispersible granules and other conventional formations. The composition of the present invention is used for prevention and treatment of crop plant diseases, and has advantages of high efficiency, low environment pollution, delaying of pathogen resistance generation, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a pesticide composition, in particular to a bactericidal composition containing toxic fluorophosphorus. Background technique [0002] Phosphate (N-[2-(4-methylbenzothiazolyl)]-2.amino-2-fluorophenyl-O,O-diethylphosphonate) is a novel fluorine-containing amino Phosphate-based new antiviral agents can increase the content of the signal molecule salicylic acid by activating the tobacco salicylic acid signaling pathway, thereby promoting the expression of downstream disease-related proteins; obtained by inducing the activities of tobacco PAL, POD, and SOD defense enzymes Antiviral ability; reduce the invasion of the virus to the host by gathering TMV particles. Because the agent is friendly to the environment, the production process is simple, there is no three-waste pollution, the production cost is lower than that of commercially available agents, and it can also improve plant di...
