Abstract
The invention belongs to pesticide field, the invention discloses a kind of herbicidal composition, contain fluometuron and acetamide-group herbicides.This herbicidal composition is mainly used in cotton field and corn field management of weeds, advantage such as have efficient, broad weed-killing spectrum, safety is higher, and cost is low, and environmental pollution is low.
Description
Technical field
The invention belongs to weed killer herbicide, relate in particular to fluometuron and amide herbicide composition.
Background technology
It is little that the hat level of coverage is planted in cotton fertility in early days, grows multiple single, double cotyledon weeds easily, and often herbicidal effect is not good to use single weed killer herbicide.But it is single that existing weed killer herbicide kind mostly is herbicidal effect, is not to prevent and kill off monocotyledon weed, can only prevent and kill off broadleaf weed exactly, even some weed killer herbicide mixture kinds are arranged, but safety is not high, easily cotton produced poisoning.
Fluometuron is one of main weed killer herbicide that is used in the cotton field, and most of weeds are had the good effect of preventing and kill off, but relatively poor to the effect of grassy weeds such as main weeds lady's-grass, and the longevity of residure is long.The inventor tests discovery, uses fluometuron fool proof to cotton in the cotton field by 120～1800 gram/hectares.Acetamide-group herbicides have the good effect of preventing and kill off to grassy weed, but easily cotton are produced poisoning when dosage is high.Therefore,, killing meeting generation complementation on the grass spectrum if fluometuron and acetamide-group herbicides are used with, and the raising of drug effect, can reduce both using dosages, safer to cotton.By retrieval, do not find that fluometuron and acetamide-group herbicides mix the report that uses.
Summary of the invention
The object of the invention provides a kind of efficient, broad weed-killing spectrum and the higher herbicidal composition of safety, is used for managements of weeds such as cotton field, corn field.

Herbicidal composition of the present invention can be applied to corn field and prevent and kill off single, double cotyledon weeds except that the cotton field, as lady's-grass, eleusine indica, barnyard grass grass, green foxtail, piemarker, Amaranthus retroflexus, black nightshade, knotweed, lamb's-quarters etc., but is not limited to above-mentioned weeds.
The present invention has compared following advantage than prior art:
(1), broad weed-killing spectrum.Adopt fluometuron to prevent and kill off broadleaf weeds such as piemarker, kitchen garden, Amaranthus retroflexus; Adopt acetamide-group herbicides to prevent and kill off grassy weeds such as eleusine indica, lady's-grass, barnyard grass grass, green foxtail, solved the monocotyledon weed and the broadleaf weed in cotton field simultaneously.
(2), drug effect height.The present invention has improved the drug effect height, has reduced the agricultural chemicals usage amount, has reduced production cost and use cost, has also reduced environmental pollution simultaneously.
(3), the longevity of residure is moderate.The fluometuron longevity of residure is long, about 100 days.And acetamide-group herbicides longevity of residure appearance is to shorter, and both use back drug effect height with, can reduce the using dosage of fluometuron, shortens the longevity of residure, avoids the harm to late stubble sensitive crop.
(4), safe.The present invention has reduced the usage amount of fluometuron and acetamide-group herbicides, and is therefore safer to cotton.

(2) experimental example
1, laboratory test
Indoor synergistic effect of the present invention is measured, adopted Colby method theory of computation growth rate, theoretical growth rate=XY/100, X and Y are respectively the percentage of medicament list time spent plant weight for contrast.Actual growth rate is synergistic effect less than theoretical growth rate, otherwise is antagonism.
Result's (seeing Table 4～table 9) shows that fluometuron uses with isopropyl methoxalamine, Acetochlor, butachlor respectively lady's-grass, piemarker and Amaranthus retroflexus are had obvious synergistic effect.
Table 4 fluometuron and isopropyl methoxalamine are used the synergistic effect to lady's-grass with
Annotate: "+" expression synergistic effect, "-" expression antagonism (down together).
Table 5 fluometuron and isopropyl methoxalamine are used the synergistic effect to piemarker, Amaranthus retroflexus with
Table 6 fluometuron and Acetochlor are used the synergistic effect to lady's-grass with
Table 7 fluometuron and Acetochlor are used the synergistic effect to piemarker, Amaranthus retroflexus with
Table 8 fluometuron and butachlor are used the synergistic effect to lady's-grass with
Table 9 fluometuron and butachlor are used the synergistic effect to piemarker, Amaranthus retroflexus with
2, field trial
Control efficiency in the field to herbicidal composition of the present invention is tested, and the computational methods of weeds preventive effect are: weeds preventive effect (%)=(X-Y)/Y*100,
X wherein: weeds fresh weight when being untreated
Y: the weeds fresh weight after the drug treating
Result's (seeing Table 10) is followed successively by the fresh weight preventive effect order of lady's-grass: 30% volt of different＞30% volt second＞30% volt of fourth＞50% Acetochlor＞72% propisochlor＞50% fluometuron＞60% butachlor; Fresh weight preventive effect order to Amaranthus retroflexus is according to this: 30% volt of different＞30% volt second＞50% fluometuron＞30% volt fourth＞60% butachlor＞72% propisochlor＞50% Acetochlor.Remove when preventing and kill off Amaranthus retroflexus, 50% fluometuron slightly is better than beyond 30% volt of fourth, and as can be seen, herbicidal composition of the present invention obviously is better than each weed killer herbicide list usefulness to the preventive effect of lady's-grass and Amaranthus retroflexus.
The effect of table 10 fluometuron and acetamide-group herbicides management of weeds lady's-grass and Amaranthus retroflexus
Annotate: volt=fluometuron; Different=isopropyl methoxalamine; Second=Acetochlor; Fourth=butachlor; Each medicament recommended dose routinely uses; Same letter is represented difference not remarkable (P=0.05).
