Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of collaboration using tembotrions and pretilachlor as active ingredient increases
Effect response composition pesticide, suitable for preventing and kill off rice terrace annual grassy weeds, especially with barnyard grass (Echinochloa
Crusgalli), short arrowhead (Sagittaria pygmaea), rhizoma alismatis (Alisma plantago-aquatica) are miscellaneous for advantage
The rice terrace annual grassy weeds of grass.
Background technology
Tembotrions (Tembotrione) are a kind of three ketones selective herbicides, 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.
Pretilachlor (Pretilachlor), is a kind of acetamide-group herbicides, and barnyard grass, bald barnyard, thousand are prevented and kill off suitable for rice
1 year raw grass such as gold, eleusine indica, needle spikesedge herb, alisma canaliculatum, water amaranth, difformed galingale herb, cyperus iria, false loosestrife, Monochoria vaginalis
Section and broad leaved weed.
By experiment, we have found that tembotrions and pretilachlor to barnyard grass (Echinochloa crusgalli,
ECHCR), Paspalum distichum (Paspalum paspaloides, PASPA), bent grass (Agrostis matsumurae,
AGRMA), wild water chestnut (Heleocharis plantagineiformis, HELPL), short arrowhead (Sagittaria pygmaea,
SAGPY), 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 synergy
Effect.
The present inventor has made intensive studies tembotrions, pretilachlor mixture, finds tembotrions, pretilachlor mixture to target
Weeds have synergistic response, especially tembotrions and pretilachlor are compounded to barnyard grass (Echinochloa crusgalli,
ECHCR), short arrowhead (Sagittaria pygmaea, SAGPY), rhizoma alismatis (Alisma plantago-aquatica, ALIPL)
With significant synergistic response.
