Switsotswani leswimbirhi kuvulavuriwa hiswona swiri swimbirhi, hikuva vusokoti nati grapevine mealy bugs swina vuxaka. Grapevine mealy bugs ti kota ku fambisiwa hi vusokoti naswona xivumbeko xa vusokoti xinga kombeta vukona bya mealybug hikuva mihandzu ya honeydew yi humesa swakudya swa vusokoti lebyi. Switsotswana swa mealybug xaxisati naxona xihumesa njara yokarhi hilaha kuhumaka matandza.
Hinkarhi lowu kuvumbekaka swivanani swisuka ematlukeni kuya eka swichocho swa madiriva. Kuva na swinwana swantima swofana na ku furha leswivaka kona eka mihandzu ya honeydew leswi humesiwaka hi mealy bug naswona muhlovo lowu wantima wunga vonaka eka misinya leyi hlaseriweke.

Xikongomelo nkulu xaku lawula kufanele kuva kusivela ti mealy bugs kuva ti hlasela swichocho swa madiriva kumbe ku hangalaka na misinya leyinwana ya madiriva, kambe kulawula vusokoti i goza rosungula eka kulawula mealybug. Plastiki leri vekiwaka eka misava leyinga hansi ka nsinya wa madiriva (soil strip directly below the vine row) ringa pfuna eka minkarhi yinwana kuva vusokoti kuva byi tshikelela kona matandza. Loko kovonaka nhlayo yikulu ya vusokoti lebyi famba fambaka ehansi ka plastiki leyi, yifanele kususiwa hiku hatlisa.
Nhova leyi milaka yikula swinene yiva yona ndlela leyi vusokoti byikotaka kunghena hiyona eka misinya ya madiriva naswona swifanele ku papalatiwa eka nguva yo byala. Kutirhisa swimilani swo seketela swinga pfuna ku lawula nhova, xikanwe naku pfuneta eka kulwisana na valala vantumbuluko ku fana na mealybug.

Masimu lawa yanga hlaseriwa ya tsariwa hinguva yobyala leswaku yata kota ku fafazeriwa hiku tirhisa tikhemikali hi xixika loko matluka yangase hluka. Swina nkoka leswaku misinya leyinga le tlhelo ka leyinga hlaseriwa nayona yitshunguriwa. Kutsakamisiwa ka kahle kuna nkoka eka masimu lawa hikuva ti mealy bugs tatumbela hi xixika ematlukeni lawa yanga fa kusuka kwalano yiya e timintswini. Laha kungana nhlaselo wukulu wa mealy bug kulaveka xidlaya switsotswana swifanele kutirhisiwa. Vekela xisivela switsotswana lexi damarhelaka kumbe letinga totiwa tikhemikali leti eka tshindi ra nsinya nale ka tinsimbhi ta nseketelo leswaku kuta lawuleka vusokoti.
