I-Whiteflies yizinambuzane ezincane ezifana nenundu, kuphela ezincane kakhulu (ubukhulu bazo abudluli u-2 mm), zimbozwe impova emhlophe noma ephuzi i-mealy. Ngesihlandlo sokuqala abalimi bezitshalo babhekana nalezi zinambuzane ema-80s ekhulwini lama-20 futhi kusukela ngaleso sikhathi akuzange kube khona ukushisa okukhulu okwakungabonakali kule nkemba.
Ama-Whiteflies enza umonakalo omkhulu ezitshalweni. Akugcini nje kuphela ukuthi bayondla ama-juice abo, futhi bayidla okungaphezu kwalokho abayidingayo ngenxa yokuphila kwabo, futhi okweqile kunikezwe phezulu kwamacembe. Kulezi amakhowe aphakathi komsoco zikhula, okuholela ekuphuleni kokuphefumula okuvamile nokuvota. Ngaphezu kwalokho, ama-whiteflies abathwala izifo ezihlukahlukene eziyingozi ezitshalweni.
Cishe wonke umuntu okhulisa imifino noma izitshalo zezimbali, ngokushesha uzobhekana nenkinga yokubhubhisa i-whitefly ekushiseni okushisa. Akulula ukwenza lokhu, futhi ukuphumelela kwezinqubo zokuvikelwa kwezitshalo ngokumelene nalezi zinambuzane kuxhomeke ezintweni eziningi, ikakhulukazi, ngokusakazeka kokutheleleka.
Ngokungangabazeki, ukuvimbela kuyindlela yokuqala futhi ebaluleke kunazo zonke okungenzeka futhi kufanele ilandele ukuvela kwenkinga yokulwa ne-whitefly ebamba lokushisa. Izinyathelo zokuvimbela zilandelayo:
- Ngokuvamile i-whitefly ihanjiswa ngaphakathi kokushisa okuvela ngaphandle uma utshala. Ngakho-ke, bahlola ngokucophelela izitshalo ezitholakalayo zokutheleleka - ukuba khona kwamaqanda ngaphansi kweqabunga lamaqabunga.
- Izicupho ezithathelanayo. Ngomsebenzi wokuvimbela, amateyipu ajwayelekile wokubamba izimpukane ezijwayelekile zihle kakhulu, kodwa ungathenga futhi okhethekile ukulwa nezinambuzane ezincelisayo ezincelisayo.
Kodwa uma i-whitefly isivele itholakale ku-greenhouse yakho ku-utamatisi, isilimo esidliwayo esinamagatsha anamanzi, i-hibiscus njalonjalo, kufanele uthathe izinyathelo ezisebenzayo zokulwa nalo, ukuze ulondoloze izitshalo.
I-Whitefly ekushiseni okushisa: izindlela zokulwa
1. Kanjani ukususa i-whitefly kusuka ekushiseni okushisa nge-mechanical method? Le ndlela ifanele uma kwenzeka ukuthi indawo ethintekile yizinambuzane ayikho enkulu kakhulu. Ngakho-ke, amaqabunga esitshalo ngasinye, anqunywe yizinambuzane ezidakayo, kufanele ahlanjwe ngesisombululo seseva, ahlanze amaqanda kuwo.
Kanye nokuvimbela, ukuqeda i-whitefly endaweni yokushisa, ungasebenzisa izicupho zeglue - ezithengiwe noma ezenziwe ngokwabo. Ukwenza kube lula: amakhadibhodi anqunywe yizikwele ezingu-8 ngo-8 sm futhi agqunywe yi-rosin, uju, i-Vaselinum. Ngokuvamile indlela ye mechanical ayisebenzisi ngokwanele futhi umuntu kufanele asebenzise izinyathelo ezengeziwe.
Izindlela zezinto eziphilayo - nazo ziphumelela esigabeni sokuqala sokutheleleka, lapho inani lezitshalo ezithathiwe lisencane. Njengoba izindlela zemvelo zomzabalazo zisetshenziswa:
- ukumnika i-dandelion - 40 g amaqabunga kanye no-30 g we-rhizomes kufanele kugcwale ilitha lamanzi futhi ufune amahora amathathu, bese uqhubeka ushicilela. Inqubo kufanele iqhutshwe njalo ngemva kwamasonto amabili kuze kuphele inkinga;
- Inkuni yokhuni - isakazeka ngokufanayo emhlabathini;
- i-garlic ukumnika - 100 g i-garlic amakhemikhali athululele 500 ml amanzi futhi afune izinsuku ezingu-4-5. Ukuze uphefaza, 5 g we-infusion kuhlanjululwa ngetitha ngalinye lamanzi.
3. Izindlela zamakhemikhali. Uma izinyathelo ezingenhla zingakusizi ukuqeda i-whitefly ebamba lokushisa, kufanele ucabange ukuthi ungabhekana kanjani nezinambuzane ngosizo lwezinambuzane. Ngakho-ke, isibonelo, abalimi abanolwazi batusa i-acta yezidakamizwa, ezibonisa ukusebenza kahle kakhulu ekulwa namagciwane. Kunconywa ukuthi ukuhlanganiswe ngenye ithuluzi - i-acticle kulawo macala uma kudingeka ukuba ususe i-whitefly ngokushesha ngangokunokwenzeka.
