Embodiment 1

[0022] Formulation example 1: 70% fenclofen-oxaprop-p-ethyl-oxafefen water-dispersible granule.

[0023] Cyclofenac 40%, Fenoxaprop-P-P-P, 25% Fenoxam, Sodium Lauryl Sulfate 5%, Fatty Amine Polyoxyethylene Ether 5%, Urea 3%, Polyvinyl Alcohol 2 %, Kaolin makes up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying , and sieve to obtain 70% cyclic ester fen-oxaprop-ethyl-oxaprop-ethyl water-dispersible granules.

Embodiment 2

[0024] Formulation Example 2: 80% cyclafen-oxaprop-ethyl-oxaprop-methyl wettable powder.

[0025] Cyclofenpyr 50%, Fenoxaprop-P-P 10%, Fenoxam 20%, Calcium Dodecyl Benzene Sulfonate 10%, Calcium Lignosulfonate 5%, and diatomaceous earth make up 100%. Mix the above active ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize and then pulverize by air flow, and mix evenly to obtain 80% fenpyrafen. Wet powder.

[0026] Formulation example 3: 24% fenclofen-oxaprop-ethyl-oxaprop-fen-oxafen oil suspension concentrate.

After the above-mentioned active ingredients, wetting agent, dispersant, thickener and liquid carrier are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system formed in a non-aqueous medium ...

Embodiment 2

[0052] Biological Assay Example 2: Field Drug Efficacy Test.

[0053] The experiment site was selected to be a paddy field with a lot of occurrences of bermudagrass, barnyardgrass and stephenia chinensis. 8 treatments were established in the test, and 3 repetitions were established for each treatment. Treatment 1 was 24% fenpyrafen·fenoxaprop-p-ethyl-oxafefen oil suspension concentrate (15% fenclofen: 2% pure Fenoxaprop: 7% fenoxaprop-methyl), treatment 2 is 17% fenoxaprop-ethyl oil suspension concentrate (15% fenoxaprop-ethyl: 2% fenoxaprop-ethyl ), treatment 3 was 22% fenoxaprop-oxaprop-oxazone oil suspension concentrate (15% fenoxafen-fen: 7% oxamifen), treatment 4 was 9% oxaprop-ethyl-oxaprop-oxaprop-ethyl Fenzafen oil suspension concentrate (2% Fenoxaprop-P-P: 7% Fenoxaprop-P-P), treatment 5 is 24.3% fenpyrafen suspension concentrate, treatment 6 is 6.9% Fenoxaprop-P-P water Emulsion, treatment 7 was 10% fenoxen emulsifiable concentrate, treatment 8 was the control (no ...

Abstract

The invention relates to a weed control composition containing pyriftalid, fenoxaprop-p-ethyl and metamifop. The active ingredients of the composition refer to the pyriftalid, the fenoxaprop-p-ethyl and the metamifop, and the weight part ratio of the pyriftalid to the fenoxaprop-p-ethyl to the metamifop is (1-20) to (1-5) to (1-15). The weed control composition disclosed by the invention has a synergetic effect and can be used for controlling annual weeds in paddy fields, the effect is obviously superior to that of single or binary mixture application of a single agent, the herbicide controlling spectrum is widened, the use amount of the pesticides is reduced, the environmental pollution is alleviated, and the drug resistance of weeds is delayed.

Description

technical field [0001] The present invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with fenpyrafen, fenoxaprop-p-ethyl and fenpyramid as active ingredients, which is mainly used for controlling rice fields Annual weed. Background technique [0002] Pyriftalid (pyriftalid): belongs to pyrimidine oxygen (thio) benzoate herbicides, its mechanism of action is to inhibit the synthesis of acetolactate synthase, it has a good control effect on barnyardgrass and stephenia in paddy fields, and it has a good effect on cloves Broad-leaved weeds and sedges such as Polygonum, broken rice sedge, cattle felt, knotweed, and bermudagrass also have certain control effects. [0003] Fenoxaprop-P-ethyl: belongs to heteroepoxyphenoxypropionic acid herbicides, mainly by inhibiting the key enzyme of fatty acid synthesis - acetyl-CoA carboxylase, thereby inhibiting the synthesis of fatty acids. Synthetic, mainly used for...
