Ngaba izilawuli zokukhula kwezityalo zingasetyenziswa kunye nezibulali zifo zokungunda?
Ngaba izilawuli zokukhula kwezityalo zingasetyenziswa kunye nezibulali zifo zokungunda?
Izilawuli zokukhula kwezityalo kunye ne-fungicides zingasetyenziswa kunye kwezinye iimeko, kodwa ingqalelo kufuneka ihlawulwe ekusebenzisaneni kunye nokhuseleko phakathi kwee-agent.
Ukuxutywa kwabalawuli bokukhula kwezityalo kunye ne-fungicides kuxhomekeke kwindlela yokwenza i-agent, i-systemic conductivity, ukuhambelana kwezinto zokulawula, kunye nokuba ukuchasana kuya kwenzeka emva kokuxuba.
Kwezinye iimeko, ezifana nokuphumeza injongo yokuthintela izifo okanye ukomeleza ukuxhathisa kwezifo zezityalo, ukukhuthaza ukukhula kwezityalo okanye ukuhlakulela izithole ezomeleleyo, izilawuli zokukhula kwezityalo zinokuxutywa nezibulala-ntsholongwane zokungunda. Umzekelo, i-auxin 2,4-D ixutywe nezibulali ntsholongwane zokungunda zokulawula ukungunda okungwevu ze emva koko zigalelwe amathupha etumata, okanye xa iimpukane ezimhlophe okanye iintwala kunye ne-downy mildew, grey mold, njl. njl. Ukulawula iimpukane ezimhlophe okanye iintwala zixutywa neearhente zokulawula ukungunda.
Nangona kunjalo, ayizizo zonke izilawuli zokukhula kwezityalo kunye nemichiza yokungunda ezinokuxutywa ngokukhuselekileyo.
Ezinye izilawuli zokukhula kwezityalo, ezifana ne-paclobutrazol, i-chlormequat, njl., ngokuqhelekileyo azikhuthazwa ukuba zixutywe kunye ne-fungicides ukuphepha imiphumo emibi. Ngaphambi kokusetyenziswa, kucetyiswa ukuba uqhube uvavanyo lokuxuba ukuqinisekisa ukuba akukho zithintelo ezimbi ngaphambi kokuxuba, kwaye ulandele umgaqo "weziyobisi ezihlukeneyo" ukuphepha ukuphendula emva kokuxuba kunye nokuchaphazela umphumo.
Ukwengeza,ingqalelo kufuneka ihlawulwe ukuhambelana amachiza xa exutywe ukuphepha iziphumo ebezingalindelekanga ebezingalindelekanga. Vavanya phambi kokusetyenziswa, kwaye ngokuthe ngcembe wandise idosi yeyeza, nikela ingqalelo kwimeko yesityalo, kwaye ulungelelanise idosi kunye nexesha lechiza ngexesha lokuqinisekisa ukhuseleko nokusebenza.
Isishwankathelo,ukuxutywa kwabalawuli bokukhula kwezityalo kunye nezibulali-ntsholongwane zokungunda kufuna ukulumka, qinisekisa ukuba ifomyula yechiza nokusetyenziswa kwayo kuyaqondwa, kwaye kancinane uzame ngedosi efanelekileyo, kwaye wenze uhlengahlengiso olufanelekileyo olusekwe kwiziphumo zolingo.
