Description
Technical field
The present invention relates to technical field of compounded pesticide more particularly to a kind of rice terrace containing benthiocarb and furans sulphur humulone to remove
Careless composition.
Background technology
In recent years, with the change of rural laborer's structure and the circulation of land management right, the planting type of rice is
Quickly tend to cultivation direction that is light-duty, simplifying transformation so that the cultivated area of Direct-seeding Rice expands rapidly.In direct seading rice field,
Since a large amount of straw-returnings, the unfavorable factors such as shallow rotation, dry-sowed waterpipe of ploughing shallowly influence, causes field grass phase is broadcast live year after year and become
Change, grass is mutually complicated, type is more, and quantity is big, and early period, weed growth was fast, and " grass takes advantage of seedling " phenomenon is serious, and weed control difficulty increases；Together
When due to resistant weed problem, multi-purpose medicine, to abuse medicine, Irrational Use of Drugs phenomenon universal, not only increases medication, recruitment cost, right
Environment brings pollution, also accelerates the development process of Weed Resistance, further increases and prevent and kill off difficulty.
Benthiocarb also known as benthiocarb, Benthiocarb, remove field green bristlegrass, English common name at weed eradication pellet：Thiobencarb, chemical name
Referred to as：S- [(4- chlorphenyls) methyl] diethyl thiocarbamate.Benthiocarb passes for carbamates selectivity interior suction
Conductivity type soil processing herbicide can be absorbed by the root of weeds and young shoot, and especially young shoot is transferred to after absorbing in plant, right
Growing point has very strong inhibiting effect.Benthiocarb can hinder alpha-amylase and protein to synthesize, the mitosis to plant cell
Also there is strong inhibition effect, thus cause the weeds at the weed seed sprouted and sprouting initial stage withered.It is miscellaneous with grass family in rice
There is higher selectivity between careless (barnyard grass, moleplant seed), the speed of weeds Assimilation and conductivity benthiocarb is faster than rice, and in vivo
The speed of degradation benthiocarb is slower than rice, this is to form selective physiological foundation.Such herbicide can be inhaled by soil rapidly
It is attached thus small with the leaching of moisture, be typically distributed across soil layer 0-2 centimeters, the suction-operated of soil reduce by evaporation and
It is lost caused by photodissociation, in the soil long half time, is 2~3 weeks under good condition of ventilating, be then 6~August under anaerobic condition,
There is the relatively long lasting period.However in practical application, benthiocarb, which only has the weeds that seed in soil is sprouted, closes down effect,
And the Weed-control effect after being unearthed to the broad leaved weeds such as triquetrousc murdannia herb, Monochoria vaginalis and sprouting is poor, generally requires secondary cauline leaf process medication
Benefit is killed.
Furans sulphur humulone is also known as special chaff ester ketone, develops code name：AVH-301, English common name：Tefuryltrione, CAS
Accession number：473278-76-1, chemical name：2- { the chloro- 4- mesyls -3- of 2- [(RS)-tetrahydrofuran -2- ylmethoxy first
Base] benzoyl } thiacyclohexane -1,3- diketone is Bayer, northern Xinghua is learned and national federations of association of agricultural cooperative society joint development
Benzoylcyclohexan dione herbicides.Furans sulphur humulone category benzoylcyclohexan dione herbicides are novel wide spectrums
Herbicide, by inhibiting HPPD (medical midbodies of para (ortho)-hydroxybenzoic acetone acid dual oxide enzyme), the final biosynthesis for influencing carotenoid.Furans
The selectivity of sulphur humulone (is metabolized as 4- hydroxyls derivative derived from its metabolic difference in rice and weeds in crop
Object), it is also possible to since crop will be slower than weeds to its Foliage Absorption.Furans sulphur humulone can by blade face and root absorption, and
Xylem and bast Xiang Ding and to base conduct, be distributed in entire plant, be mainly used for preventing and kill off rice terrace broad leaved weed and nutgrass flatsedge
Section weeds are general to grassy weed effect.Weeds are after by medicine, blade face albefaction, then separate living tissue necrosis.Furans sulphur humulone can
Early stage weeds were handled after weeds Seal treatment and seedling before seedling, to Monochoria vaginalis, Procumbent Falsepimpernel, Monochoria korsakowii, rhizoma alismatis, auricle water amaranth etc. 1 year
Raw broad leaved weed, the awns such as firefly Lin, Herba Cyperi Glomerati cyperus iria category weeds and short arrowhead, the open country for generating resistance to sulfonylurea in recent years
The broad leaved weeds such as arrowhead, water chestnut are largely effective.In addition, special miscellaneous to triquetrousc murdannia herb, ambatch, sweet wine intestines, bur beggar-ticks, big bur beggar-ticks etc.
The paddy land weeds such as grass and fake rice, Rong's grass have extensive preventive effect.The active ingredient is being prevented and kill off to ALS herbicides generation resistance
It is largely effective in terms of weeds.Furans sulphur humulone is in the paddy field lasting period up to 45~50 days.However, furans sulphur humulone contains rice terrace
The grassy weed effects such as capable barnyard grass, moleplant seed are general, often used with other composite reagents in practical application.
It is well known that Herbicid resistant is global challenges, all resistant weeds case history in all parts of the world crop producing region,
These weeds are best to current agriculture field, mechanism of action herbicide (MoA) that is most relying on generates resistance.However, using complete
The date that new role mechanism herbicide solves Weed Resistance is gone for ever.Currently, effective resistant weed administering method master
It uses：First, taking different role mechanism herbicide mixture, achieve the purpose that effectively to control weeds and delaying drug resistance development；Again
Person is exactly that weeds early stage is taken to administer, and is handled in the stage (closing) of weeds most fragile, achieves effective control weeds and reduces miscellaneous
The purpose of radix occurs for grass.
The prior art is in order to prevent and kill off rice field grassy weed, broad leaved weed, sedge weed and effectively solve resistant weed
Problem is all made of above-mentioned two kinds of weed control methods.But the problem is that：When Seal treatment, since different weeds emerge
Peak is different, as barnyard grass, moleplant seed 3-10 days after broadcasting are unearthed peak, sedge weed, broad leaved weed in grassy weed
Out of grass to be unearthed within 15 days to 25 days after generally broadcasting late, the closing medication phase is difficult to take into account, and often needs secondary medication；Second is that stem
Leaf processing, since weeds radix is big, grass is mutually complicated, and careless age differs, and cauline leaf process need to increase dosage, and effect is poor.It is practical raw
2-3 medication is generally required in production, could solve all weeds, and medication and recruitment cost are big.How designing one kind and can reducing makes
