Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of collaboration using ring sulphur ketone and butachlor as active ingredient increases
Effect response composition pesticide, suitable for preventing and kill off rice terrace annual grassy weeds, especially with Paspalum distichum (Paspalum
Paspaloide), arrowhead (Sagittaria trifolia), rhizoma alismatis (Alisma plantago-aquatica) are miscellaneous for advantage
The rice terrace annual grassy weeds of grass.
Background technology
Ring sulphur ketone (Tembotrione) is a kind of three ketones selective herbicide, can effectively prevent main broadleaved herb and
Some grassy weeds, such as piemarker, three-coloured amaranth, lamb's-quarters, knotweed, barnyard grass, lady's-grass have preferable control effect, at closing before bud
Cauline leaf process after reason and bud.
Butachlor (Butachlor) is a kind of acetamide-group herbicides, can prevent and kill off barnyard grass, lady's-grass grass, green bristlegrass, fescue,
Annual gramineous weeds and some broadleaf weeds such as Monochoria vaginalis, Drilgrass, special-shaped sand-grass.Suitable for cabbage, beans dish, trailing plants
Foretell the vegetable farm herbicides such as class, wild cabbage class, solanaceous vegetables, spinach.
By experiment, we have found that ring sulphur ketone and butachlor to barnyard grass (Echinochloa crusgalli,
ECHCR), Paspalum distichum (Paspalum paspaloides, PASPA), moleplant seed (Leptochloa chinensis,
LEPCH), the nit careless (Leptochloa panicea, LEPPA), wild water chestnut (Heleocharis plantagineiformis,
HELPL), short arrowhead (Sagittaria pygmaea, SAGPY), arrowhead (Sagittaria trifolia, SAGTR) dayflower
(Commelina communis, COMCO), Monochoria korsakowii (Monochoria korsakowii, MONKO), Herba Cyperi Glomerati
(Juncellus serotinus, JUNSE), cyperus iria (Cyperus iria, CYPIR), triquetrousc murdannia herb (Murdannia
Triquetra, MURTR), rhizoma alismatis (Alisma plantago-aquatica, ALIPL) have synergistic function.
The present inventor has made intensive studies ring sulphur ketone, butachlor mixture, finds ring sulphur ketone, butachlor mixture to target
Weeds have synergistic response, especially ring sulphur ketone and butachlor are compounded to Paspalum distichum (Paspalum paspaloides,
PASPA), arrowhead (Sagittaria trifolia, SAGTR), rhizoma alismatis (Alisma plantago-aquatica, ALIPL) tool
There is significant synergistic response.
The content of the invention
It is low, anti-with notable synergistic function, expansion herbicide controlling spectrum, use cost it is an object of the invention to provide one kind
Control that effect is good, Herbicidal combinations containing ring sulphur ketone and butachlor of safety and environmental protection.
The technical scheme is that：A kind of Herbicidal combinations containing ring sulphur ketone and butachlor, active ingredient is by ring sulphur
