Daawooyinka loo yaqaan 'Aryloxyphenoxypropionate herbicides' waa mid ka mid ah noocyada caadiga ah ee suuqa dhir-daaweedka adduunka…

Tusaale ahaan 2014, iibka caalamiga ah ee aryloxyphenoxypropionate herbicides wuxuu ahaa US$1.217 bilyan, taasoo u dhiganta 4.6% ee US$26.440 bilyan suuqa dhiraynta dhirta iyo 1.9% US$63.212 bilyan suuqa sunta cayayaanka.In kasta oo aanay u fiicneyn dawooyinka herbicides sida amino acids iyo sulfonylureas, waxa ay sidoo kale boos ku leedahay suuqa dhir-dhimista (oo lagu qiimeeyay kaalinta lixaad ee iibka caalamiga ah).

 

Aryloxy phenoxy propionate (APP) herbicides waxaa inta badan loo isticmaalaa xakameynta cawska cawska.Waxaa la helay 1960-yadii markii Hoechst (Jarmalka) ay ku bedeshay kooxda phenyl ee qaab dhismeedka 2,4-D oo leh diphenyl ether waxayna soo saartay jiilkii ugu horreeyay ee aryloxyphenoxypropionic acid herbicides."Grass Ling".Sannadkii 1971, waxaa la go'aamiyay in qaab dhismeedka giraanta waalidku ka kooban yahay A iyo B. Daawooyinka dhirta ee soo socda ee noocaan ah ayaa wax laga beddelay iyada oo lagu salaynayo iyada oo lagu beddelayo giraanta A benzene ee hal dhinac oo loo beddelo giraanta heterocyclic ama isku dhafan, iyo soo bandhigida kooxaha firfircoon sida F. atamka galay giraanta, taasoo keentay in taxane ah oo badeecooyin leh hawl sare., daawooyin herbicides badan oo door ah.

Taariikhda horumarinta ee propionic acid herbicides

 

Habka wax-qabadka

Aryloxyphenoxypropionic acid herbicides ayaa inta badan horjoogayaasha firfircoon ee acetyl-CoA Carboxylase (ACCase), taas oo ka hortagaysa isku dhafka acids dufanka leh, taasoo keentay isku dhafka oleic acid, linoleic acid, linolenic acid, iyo lakabyada waxy iyo geeddi-socodka goynta ayaa xannibay, taasoo keentay in degdeg ah burburinta qaab dhismeedka xuubka dhirta, korodhka qulqulka, iyo ugu dambeyntii dhimashada geedka.

Astaamaha waxtarka sare leh, sunta hooseeya, xulashada sare, badbaadada dalagyada iyo nabaad-guurka fudud ayaa si weyn kor ugu qaaday horumarinta dhirta dhirta.

Muuqaal kale oo ka mid ah AAP herbicides waa in ay si muuqaal ah u firfircoon yihiin, taas oo lagu garto isomers kala duwan oo hoos yimaada qaabdhismeedka kiimikada, iyo isomers kala duwan ayaa leh hawlo dhireed oo kala duwan.Waxaa ka mid ah, R (-) -isomer waxay si wax ku ool ah u joojin kartaa dhaqdhaqaaqa enzyme bartilmaameedka, xannibaya samaynta auxin iyo gibberellin ee haramaha, oo muujiya firfircoonida geedaha yaryar, halka S (+) -isomer asal ahaan aan waxtar lahayn.Farqiga waxtarka u dhexeeya labada waa 8-12 jeer.

Daawooyinka herbicides-ka ganacsiga ee APP waxaa sida caadiga ah lagu farsameeyaa esters, taasoo ka dhigaysa inay si fudud u nuugaan haramaha;si kastaba ha ahaatee, esters caadi ahaan waxay leeyihiin milmayn yar iyo adsorption xoog badan, sidaa darteed ma fududa in la daadiyo oo si fudud ayay u nuugaan haramaha.ciidda dhexdeeda.
