Embodiment 1

[0039] Example 1: 70% fenflumezone·octanoyl bromoxynil wettable powder

[0040] Mefentrazone 69%

[0041] Bromoxynil 1%

[0042] Naphthalenesulfonate Dispersant 6%

[0043] Sodium lignosulfonate 6%

[0044] Sodium Lauryl Sulfate 2%

[0045] Silica 3%

[0046] Attapulgite make up to 100%

[0047] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by a superfine pulverizer, the 70% oxaflumezone·octanoyl bromoxynil wettable powder is obtained.

[0048]The 70% oxentrazone·octanoyl bromoxynil wettable powder prepared in this example 1 is applied to the prevention and control of annual broad-leaved weeds and gramineous weeds in spring wheat fields. The nitrile wettable powder is diluted with water by 8000 times and sprayed, and the comprehensive control effects on annual broad-leaved weeds and grass weeds are above 94.3% and 92.8% respectively 15 days after application. 30% fenflumezone su...

Embodiment 2

[0049] Example 2: 36% fenflumezone·octanoyl bromoxynil suspension concentrate

[0050] Mefentrazone 35%

[0051] Bromoxynil 1%

[0052] Styrylphenol ethoxylates 3%

[0053] Polycarboxylate Dispersant 3%

[0056] Defoamer 0.3%

[0057] Sodium Benzoate 0.4%

[0058] Xanthan Gum 0.1%

[0059] Propylene Glycol 5%

[0060] Water to make up to 100%

[0061] Mix the active ingredient, dispersant, wetting agent, antifreeze agent, thickener, defoamer and water according to the ratio of the formula, and grind it with a sand mill to obtain 36% fenflumezone octanoyl Bromoxynil Suspending Concentrate.

[0062] The 36% fenflumezone·octanoyl bromoxynil suspension concentrate prepared in Example 2 was used to control annual broad-leaved weeds and gramineous weeds in corn fields. Dilute 36% oxentrazone-octanoyl bromoxynil suspension concentrate 5000 times with water and spray, and the comprehensive c...

Embodiment 3

[0063] Example 3: 20% fenflumezone-octanoyl bromoxynil emulsion in water

[0064] Mefentrazone 19%

[0065] Bromoxynil 1%

[0066] Xylene 8%

[0067] Methanol 8%

[0068] Calcium dodecylbenzenesulfonate 3.5%

[0069] Styrylphenol ethoxylates 4 %

[0070] Castor Oil Ethoxylates 3%

[0071] Xanthan Gum 0.15%

[0072] Sodium Benzoate 0.2%

[0073] Propylene Glycol 5%

[0074] Water to make up to 100%

Abstract

The invention discloses a composite pesticide composition containing topramezone and bromoxynil octanoate and a preparation thereof. The composite pesticide composition contains effective components of topramezone and bromoxynil octanoate, wherein the weight ratio of the topramezone to the bromoxynil octanoate is (70:1)-(1: 70). The composite pesticidal composition has an obvious synergistic effect, realizes combined prevention of annual broadleaf weeds and grass weeds, reduces the pesticide amount, reduces the pesticide burden on a farmer and the environment pollution, and has wide developmental and promotional prospects.

Description

technical field [0001] The present invention relates to a herbicidal pesticide composition, in particular to a compound pesticide composition containing fenfentrazone and bromoxynil octanoyl and its preparation. Background technique [0002] In recent years, due to the extensive use of various pesticides, the resistance of agricultural weeds has become higher and higher, and weeds are common and various in variety. Setaria, Brachiaria, Goosegrass, Wild Millet, Mountain Pennisetum, Tribulus terrestris, Shaped Sedge, Broken Rice Grass. Main broad-leaved weeds: amaranth, Polygonum, Chenopodium, Cocklebur, Solanum nigrum, Abutilon, Datura, Weasel petal flower, Matricaria, ragweed, wild mustard, wild carrot, echinocarpus, hard burr chrysanthemum, annual Mountain indigo, South American mountain leech, a little red, hyssop chrysanthemum, pseudophysalis, commelina, mother grass, and spring grass. In the control of chemical agents, the herbicides used for stem and leaf treatment ma...
