Isoxaflutole HPPD inhibitor herbicide ee xakamaynta haramaha

Sharaxaada badeecada

Isoxaflutole waa herbicide nidaamsan - waxaa loo beddelaa dhammaan geedka ka dib nuugista xididdada iyo caleenta waxaana si degdeg ah loogu beddelaa planta ilaa diketonitrile bayooloji firfircoon, kaas oo markaa lagu sumeeyo dheef-shiid kiimikaad aan firfircoonayn, 2-methylsulphonyl-4-trifluoromethylbenzoic acid.Dhaqdhaqaaqa alaabtu waa iyada oo la xakameynayo enzyme p-hydroxy phenyl pyruvate dioxygenase (HPPD), taas oo u beddesha p-hydroxy phenyl pyruvate ilaa homogentisate, tallaabo muhiim ah oo ku saabsan biosynthesis plastoquinone.Isoxaflutole waxay xakameysaa caws kala duwan oo caws ah iyo caws ballaaran iyadoo ay xaaqinayso cawska soo baxaya ama soo baxay ka dib qaadashada herbicide ee nidaamka xididka.Ka dib qaadashada foliar ama xididka, isoxaflutole si degdeg ah ayaa loogu beddelaa derivative diketonitrile (2-cyclopropyl-3- (2-mesyl-4-trifluoromethylphenyl) -3-oxopropanenitrile) iyadoo la furayo giraanta isoxazole.

Isoxaflutole waxaa lagu dabaqi karaa soo bixitaan ka hor, hore-u-beeris ama dhir hore oo lagu daray galleyda iyo soo-baxa kahor ama horraantii-soo-baxa ka dib ee sonkorta sonkorta.Heerka sare ayaa looga baahan yahay codsiyada ka-hor-abuurka.Tijaabooyinkii goobta, isoxaflutole waxa ay siisay heerar la mid ah xakamaynta daawaynta herbicide caadiga ah laakiin heerarka codsiga ku dhawaad ​​50 jeer ka hooseeya.Waxay xakamaysaa haramaha u adkaysta triazine marka kaligaa la isticmaalo iyo marka la isku daro.Shirkaddu waxay ku talinaysaa in loo isticmaalo isku-dhafka, iyo wareegga ama isku xigxiga leh herbicides kale si loo daahiyo bilawga caabbinta.

Isoxaflutole, oo leh nus-nololeedka 12 saacadood ilaa 3 maalmood, taas oo ku xidhan nooca ciidda iyo arrimo kale, sidoo kale waxay isu beddeshaa diketonitrile ee ciidda.Isoxaflutole waxaa lagu hayaa oogada ciidda, taasoo u oggolaanaysa in lagu qaado iniinaha cawska ee biqilka, halka diketonitrile, oo leh nus-nololeed 20 ilaa 30 maalmood ah, ayaa soo gasha ciidda waxaana la qaadaa xididdada dhirta.Dhirta iyo ciidda labadaba, diketonitrile waxaa loo beddelaa benzoic acid-ka aan firfircoonayn.

Alaabtan waa in aan lagu marsiin carrada bacaadka ah ama dhoobada leh ama carrada leh wax ka yar 2% maadada organic.Si looga hortago sunta ka iman karta kalluunka, dhirta biyaha iyo xididdada laf-dhabarta, 22 mitir ayaa loo baahan yahay si loo ilaaliyo meelaha xasaasiga ah, sida dhulka qoyan, balliyada, harooyinka iyo webiyada.
