Problems solved by technology

Due to the long-term use of these agents, they have produced different degrees of drug resistance, and the control effect is reduced.
At the same time, the extensive use of medicaments increases pesticide residues, endangers food safety, and aggravates environmental pollution.

Embodiment 1

[0030] The inventor has carried out a large amount of indoor bioassays and field efficacy tests, and the results show that after the activated ester is mixed with tridemorpholine or fenfenmorpholine or dodecamorpholine in a certain ratio, it is effective against powdery mildew, rust etc. Diseases have a significant synergistic effect. Rather than a simple addition of the two agents (see Bioassay Example 1 for details). Biological Assay Example 1: Indoor Toxicity Determination of Activated Ester and Tridemorph or Fenfenmorph or Dodecylmorpholine Compound to Wheat Powdery Mildew Bacteria

[0031] Test object: wheat powdery mildew (collected from the field)

[0032] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Select potted wheat seedlings at the 3-4 leaf stage with consistent growth potential, and select 5 pots for each treatment, numbered for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot....

Embodiment 2

[0068] Embodiment 2: 40.4% activated ester · tridemorpholine suspending agent

[0069] Activated ester 0.4%, trimorpholine 40%, polycarboxylate (dispersant) 10%, tea dry powder (wetting agent) 3%, polyvinyl alcohol (thickener) 2%, bentonite (thickener) ) 1%, ethylene glycol (antifreeze) 5%, and water to make up to 100%.

[0070] This embodiment is applied to the prevention and treatment of wheat rust. The test site is Lanzhou, Gansu. Apply the first medicine at the early stage of the onset, and carry out the second medicine seven days later. Investigate the condition index before the medicine and seven days after the second medicine. Embodiment 2 is processed by 100g (a.i.) / ha, and the control effect of 14 days after the medicine is 89.6%; 50% activated ester wettable powder is by 50g (a.i.) / ha and 75% tridemorphic emulsifiable concentrate by 375g (a.i.) / ha treatment, the control effects were 77.2% and 79.5% 14 days after treatment. The synergistic effect is obvious afte...

Embodiment 3

[0071] Embodiment 3: 30.3% activated ester · fenpropimorph suspension concentrate

[0072] Activated ester 30%, fenpropimorph 0.3%, sodium lignosulfonate (dispersant) 10%, saponin powder (wetting agent) 3%, xanthan gum (thickener) 2%, polyvinyl alcohol (thickener) 1%, propylene glycol, (antifreeze agent) 5%, water to make up to 100%.

[0073] This embodiment is applied to control sugar beet powdery mildew. The test site is Jixi, Heilongjiang. Apply the first medicine at the early stage of the onset, and carry out the second medicine eight days later. Investigate the condition index before the medicine and eight days after the second medicine. Embodiment 3 is processed by 48g (a.i.) / ha, and the control effect of 16 days after the medicine is 91.3%; 50% activated ester wettable powder is by 50g (a.i.) / ha and 75% fenpropimorph emulsifiable concentrate by 750g (a.i.) / ha treatment, the control effects were 78.6% and 82.1% at 16 days after treatment. After the combination of a...

Abstract

The invention relates to an acibenzolar-containing ssterilizing composition, which comprises the following active ingredients: the acibenzolar (A) and a morpholine bactericide (B). The morpholine bactericide is selected from tridemorph, fenpropimorph, and dodemorph; the mass ratio of A to B is 100:1-1:100; and the active ingredients account for 20 to 80 mass percent of the composition. The composition can be prepared into a suspension agent, a wettable powder, a water dispersible granule and other formulations. The sterilizing composition can be applied to farmlands, gardens and other places, and is used for preventing and controlling various plant diseases of crops such as grains, vegetables, flowers and the like, particularly powdery mildew and rust diseases.

Description

technical field [0001] The invention relates to a fungicide composition, especially a fungicide composition containing activated ester and a morpholine fungicide, and belongs to the field of agricultural fungicides. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. Powdery mildew is widespread all over the world, especially in dicotyledonous plants. The main powdery mildews in China include cereal powdery mildew caused by Ery-siphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea; Grape powdery mildew caused by Uncinula necator; powdery mildew of more than 80 kinds of trees such as mulberry, pear, persimmon, walnut, chestnut, litchi and papaya caused by Phyllactinia corylea; Powdery mildew of Rosa flowers caused by Sphaerotheca pannosa. [0003] When the powdery mildew first occurs, the leaves produce small yellow spots, and then expand and develop into round or ova...
