Description
Technical field
The present invention relates to pesticide fields, and in particular to a kind of composition pesticide containing isoxaflutole and its application.
Background technique
Isoxaflutole is to develop isoxazole herbicide by Rhone-Poulenc.Chemical name is：5- cyclopropyl
Base -1,2- oxazole -4- base (α, α, α,-trifluoromethyl -2- mesyl p-methylphenyl) ketone, molecular formula C15H12F3NO4S,
Molecular weight is 359.4, and structural formula is：
Isoxaflutole is medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme inhibitor, i.e. HPPD inhibitor.Its action character is
It can be used after activity of weeding, Miao Qianmiao with wide spectrum, death after albefaction occur in weeds.Though its symptom and carotenoid are raw
The effect symptom of object synthetic inhibitor is extremely similar, but its chemical structure feature such as polarity and degree of ionization and known carotenoids
Plain biosynthesis inhibitor etc. has apparent difference.Isoxaflutole mainly works via weeds young root Assimilation and conductivity, quick
Sense weeds pass through the synthesis for inhibiting p-hydroxybenzene pyruvic acid (HPP) ester dual oxide enzyme after absorbing this medicine, lead to the product of tyrosine
It is tired, so that the biosynthesis of plastid a kind of jade and tocopherol is obstructed, and then influence the biosynthesis of carotenoid.
Smetolachlor is the chloroacetanilide herbicides developed by Syngenta company.Chemical name is：(aRS,
1R) the chloro- 6 '-ethyl-N- of -2- (2- methoxyl group -1- Methylethyl) acetyl ortho-aminotoluene or the chloro- 6 '-ethyl-of (aRS, 1S) -2-
N- (2- methoxyl group -1- Methylethyl) acetyl ortho-aminotoluene, molecular formula C15H22ClNO2, molecular weight 283.8, structural formula
For：
Smetolachlor is mainly the growth by hindering the synthesis of protein to inhibit cell.Pass through the children of plant
The hypocotyl absorption conduction upwards of bud, that is, monocotyledonous plumule, dicotyledon, seed and root also Assimilation and conductivity, but suction
Receipts amount is less, and conduction of velocity is slow.Conduction upwards is absorbed mainly by root after emergence, inhibits the growth of young shoot and root.Susceptible weeds exist
After germination be unearthed before or just be unearthed be poisoned to death immediately, show as tooth sheath hard-pressed bale growing point, slightly thicker, radicle is thin and curved
Song, no fibrous root, gradually browning color, black rot growing point.
Isopropyl methoxalamine is the chloroacetanilide herbicides developed by Syngenta company.Chemical name is：(aRS,
1RS) the chloro- 6 '-ethyl-N- of -2- (2- methoxyl group -1- Methylethyl) its molecular formula of acetyl ortho-aminotoluene is C15H22ClNO2, point
Son amount is 283.8, and structural formula is：
Isopropyl methoxalamine is mainly the growth by hindering the synthesis of protein to inhibit cell.It is by the young shoot of plant
The hypocotyl absorption conduction upwards of monocotyledonous plumule, dicotyledon, seed and root also Assimilation and conductivity, but uptake
Less, conduction of velocity is slow.Conduction upwards is absorbed mainly by root after emergence, inhibits the growth of young shoot and root.Susceptible weeds are being germinateed
Be unearthed before being unearthed afterwards or just and be poisoned to death immediately, show as tooth sheath hard-pressed bale growing point, slightly thicker, radicle is thin and is bent,
Without fibrous root, gradually browning color, black rot growing point.
Propisochlor is by the chloro-acetyl amine herbicide of nitridation joint-stock company of Hungary exploitation.Chemical name is：2-
Chloro- 6 '-ethyl-N- isopropoxymethyl its molecular formula of acetyl ortho-aminotoluene is C15H22ClNO2, molecular weight 283.8, structural formula
For：
Propisochlor is mainly the growth by hindering the synthesis of protein to inhibit cell.Medicament is inhaled by plant plumule
Receive, into plant in protease inhibition synthesis, bud and root stop growing, and adventitious root can not be formed.Monocotyledon passes through embryo
Bud scale, dicotyledon then absorb through hypocotyl, conduct then up, seed and root also Assimilation and conductivity, but uptake is less, passes
It is slow to lead speed, root to be leaned on to absorb conduction upwards after emergence.If soil moisture is suitable for not being unearthed the weed bud phase to be killed.
