Embodiment 1

[0023] Example 1: 51% Fluoramide · Kresstrobin wettable powder

[0024] Fluoramide 50%

[0025] Kresoxim-methyl 1%

[0026] Chaku powder (wetting agent) 7%

[0027] Sodium lauryl sulfate (wetting agent) 2%

[0028] Sodium lignosulfonate (dispersant) 5%

[0029] Bentonite (filler) 10%

[0030] Attapulgite (filler) made up to 100%.

[0031] The active ingredients, various additives and fillers are fully mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, a 51% Fluoramide Kresstrobin wettable powder can be obtained.

[0032] This embodiment is applied to the control of rice sheath blight. 51% Fluoramide · Kresoxim-methyl wettable powder was diluted with water at 150ga.i. / ha [a.i., active ingredient, active ingredient] and sprayed, and the control effects were 88.4% and 90.1% after 7 days and 14 days after application. The azoxystrobin in this example can be replaced by methoxystrobin fungicides such as azoxystrobin, tri...

Embodiment 2

[0036] Example 2: 42% Fluoramide Azoxystrobin Suspension Concentrate

[0037] Fluoramide 40%

[0038] Azoxystrobin 2%

[0039] Sodium methylnaphthalene sulfonate formaldehyde condensate (wetting agent) 7%

[0040] Xanthan gum (thickener) 2%

[0041] Bentonite (thickener) 1%

[0042] Nongru 600# Phosphate (dispersant) 3%

[0043] Glycerol (antifreeze) 5%

[0044] Water Make up to 100%.

[0045] Mix the active ingredient, dispersant, thickener, wetting agent, antifreeze agent and water according to the proportion of the formula, and grind and / or high-speed shear to obtain a 42% suspension of azoxystrobin agent.

[0046] This embodiment is applied to the control of rice sheath blight. 42% Fluoramide·Azoxystrobin Suspension Concentrate is diluted with 80g a.i. / ha and sprayed with water, and the control effects are 90.8% and 91.4% respectively 7 days and 14 days after application. Azoxystrobin in this example can be replaced by methoxystrobin fungicides such as kysstrobin,...

Embodiment 3

[0050] Example 3: 33% Fluoramide · Enoxastrobin Suspension Concentrate

[0051] Fluoramide 30%

[0052] Ethoxystrobin 3%

[0053] Sodium lignosulfonate (dispersant) 5%

[0054] Chaku powder (wetting agent) 5%

[0055] Bentonite (thickener) 2%

[0056] Magnesium aluminum silicate (thickener) 1%

[0057] Ethylene glycol (antifreeze) 5%

[0058] Water Make up to 100%.

[0059] Mix the active ingredient, dispersant, thickener, wetting agent, antifreeze agent and water according to the proportion of the formula, and then grind and / or high-speed shear to get 33% fluamide enoxastrobin suspending agent.

[0060] This embodiment is applied to the control of rice sheath blight. 33% Fluoramide·Entristrostrobin Suspension Concentrate was diluted with water at 100ga.i. / ha and sprayed, and the control effects were 91.8% and 93.2% at 7 days and 14 days after application. In this example, methoxystrobin can be replaced by methoxystrobin fungicides such as kresstrobin, methoxystrobin, a...

Abstract

The invention discloses a synergistic fungicide composition, the active components of which are flutolanil and any strobilurin fungicide, and the weight proportion between the flutolanil and the strobilurin fungicide is 50:1 to 1:50. The strobilurin fungicide is chosen from azoxystrobin, kresoxim methyl, SYP-1620, trifloxystrobin, enestroburin, ZJ0712, pyraclostrobin and the like. The composition can be used to control diseases caused by rhizoctonia, and in particular, the composition has a good control effect on rice sheath blight.

Description

Technical field [0001] The invention relates to a pesticide composition, especially a synergistic pesticide composition containing fluoramide, which is mainly used for preventing and treating rice diseases. Background technique [0002] Rice sheath blight is a global disease caused by the soil fungus Rhizoctonia solani that seriously restricts rice production. It has wide distribution, large occurrence area, strong epidemic, and serious harm. It is one of the three major diseases of rice. . In recent years, with the promotion of dwarf and hybrid rice varieties and the improvement of dense planting and fertilization levels, the degree of damage is increasing year by year, seriously affecting the yield and quality of rice. Chemical control is the main means of plant disease control. However, the currently used fungicides such as carbendazim and Jinggangmycin are not effective in controlling plant diseases. At the same time, due to long-term overuse of these agents alone, the ...
