Description
Technical field
The invention belongs to pesticide herbicide technical field, more particularly to the agent for removing grass in paddy field of a kind of fluorinated ketones contained sulphur grass amine combines
Object.
Background technology
Rice is one of the staple food crop in China, and rice is the staple food of national about 60% population, and sown area is about
The 18.5% of national total sown area is accounted for, rice yield accounts for the 39.23% of total grain output, therefore the increase and decrease tool of the yield of rice is lifted
The influence of sufficient weight.But all the time, all kinds of weeds affect the yield of rice, according to investigations, its rice of the field of weed encroachment
Production loss is generally in 10-20%, serious loss 40-50%.In recent years, a kind of saving of labor, the live streaming of water-saving planting patterns
Rice rises rapid, and management of weeds, which more seems, to be even more important, wherein be affected and it is more difficult it is anti-be barnyard grass, moleplant seed etc.
The broad leaved weeds such as grassy weed, followed by Monochoria vaginalis, mexicana, potamogeton grass.Lag, kind are compared in herbicide for paddy field development
Seldom, the wider of application is bensulfuron-methyl, Acetochlor, dimethyl tetrachloride etc., but since these service life of the products are longer, weeds
Produce drug resistance, and they to barnyard grass, moleplant seed, the effect is unsatisfactory.
Fluorine ketone sulphur grass amine is acetolactate synthestase (ALS) inhibitor, by preventing valine, leucine, isoleucine
Biosynthesis, inhibit cell division and plant growth.Based on root system and young shoot absorption, has both cauline leaf and absorb activity of weeding.
Dosage is 25~50g/hm2, early application before bud or after bud is miscellaneous for preventing and kill off rice terrace grassy weed, nutgrass flatsedge and broad-leaved
Grass.
Benthiocarb is carbamates selectivity inner sucting conduction type soil processing herbicide, can be by the root of plant and children
Bud absorbs, and especially young shoot is transferred to after absorbing in plant, occupies very strong inhibiting effect to growth.Benthiocarb hinders α-shallow lake
Powder enzyme and protein synthesis, also have strong inhibition effect to the mitosis of plant cell, thus lead to the weed seed sprouted
It is withered with the weeds at the initial stage of sprouting.The speed of barnyard grass Assimilation and conductivity benthiocarb is faster than rice, and degradation in vivo benthiocarb
Speed is slower than rice, this is to form selective physiological foundation, and such herbicide can be rapidly by adsorption by soil, thus with moisture
Leaching it is small, be typically distributed across at soil layer 2cm.The suction-operated of soil reduces loses as caused by evaporation and photodissociation.?
Half-life period in soil, ventilate good condition under be 2~3 weeks, under anaerobic condition then be 6~8 months.Benthiocarb makees processing soil treatment agent
It uses, to rice safety, has excellent control effect to barnyard grass.The scope of application be suitable for rice, wheat, soybean, peanut, corn,
Vegetable fields and orchard etc. prevent and kill off barnyard grass, fescue, difformed galingale herb, moleplant seed, lady's-grass, yard grass, green bristlegrass, cyperus iria, horse
Tooth grass, amur foxtail etc..
Molinate is the selective herbicide for preventing and kill off rice barnyard grass.Medicament is absorbed by weeds bud scale and primary root, suppression
Alpha-amylase activity processed prevents protein from converting, and to make proliferative cell cannot get plasm, young leaves cannot be grown, and be caused miscellaneous
It is careless dead.Barnyard grass is prevented and kill off for rice terrace, has special efficacy to big barnyard grass.Molinate specially removes the various environmental barnyard grasses of 1~4 leaf phase of rice terrace
Grass, 15~35g of medication active ingredients/100m2, 30~40d of lasting period.If used in seedling stage, when rice seedling bed or the seedling that field is broadcast live are long
To more than 3 leaves, when 2~3 leaf phase of field barnyard grass, to water spray or pesticide-clay mixture is made spreads fertilizer over the fields with 15~22.5mL of molinate missible oil, field
Between water layer 3cm or so, and keep 5~7d, also can be before broadcasting or transplanting Honda uses.
Invention content
The purpose of the present invention is be just to provide a kind of synergistic effect significantly, the fluorinated ketones contained sulphur for rice terrace of broad weed-killing spectrum
The Herbicidal composition for rice field of careless amine.
The present invention takes following scheme to realize：

Two, indoor biological determination of activity：
Below by way of fluorine ketone sulphur grass amine, benthiocarb or molinate composition herbicide to paddy field weed indoor biological activity
It measures to verify the reasonability of formula.
In the present composition, fluorine ketone sulphur grass amine (96% active compound) is produced by Bayer joint-stock company, and (93% is former for benthiocarb
Medicine) it is produced by Lianyun Harbour Niu Taike Chemical Co., Ltd.s.Molinate (99% active compound) is by Lianyun Harbour Niu Taike Chemical Co., Ltd.s
Production.
Test method is to use greenhouse pot culture method, and quantitative weeds (per 40 plants of basin) and rice paddy seed are sowed in basin, is waited for
When weeds are grown after being unearthed to the 2-4 leaf phases, cauline leaf spraying treatment is carried out with spraying machine, is placed in greenhouse and continues after 6 hours after processing
Culture observation, investigates the preventive effect to weeds and the safety to rice after 15 days.Investigation method uses absolute value investigation method,
The fresh weight per basin remaining weeds is first investigated, then the fresh weight preventive effect of each processing is calculated according to the following formula：E=(C-T)/C × 100%,
E is fresh weight preventive effect in formula, and C is control weeds fresh weight, and T is processing weeds fresh weight.Then weeds activity is examined with Colby methods
It surveys and the co-toxicity of weeds is acted on, by Colby methods, work as E0-E>10% is synergistic effect；Work as E0-E<- 10% is antagonism；
As -10%≤E0- E≤10% is addition.
Table 1：Herbicidal composition acts on (spray-on process) to the co-toxicity of barnyard grass
It can be seen that from upper table, when fluorine ketone sulphur grass amine, benthiocarb (or molinate) compound, to the E of barnyard grass0- E values are
Between 9.76-20.35, synergy type is synergistic effect, with the weight ratio of fluorine ketone sulphur grass amine, benthiocarb for 8：22：2
Effect is most apparent, E0- E values are 20.35.
Three, test examples：
