Zvirimwa zvinogona kukanganiswa nehuzhinji hwehutachiona uye zvipembenene muhupenyu hwavo hwese. Kusiyana nemhuka, havakwanise kuzvidzivirira sezvatinoita, uye chepfu iyo vazhinji vavo vanayo dzimwe nguva haigone kushanda sezvavanofanira kuita, kunyanya kana Gardama muvengi wako.
Ichi chipembenene muchikamu chayo chevakuru hachikonzere chero matambudziko, asi mabuvi ayo anogona kuuraya zvidiki zvidiki mumazuva mashoma. Ungavarwisa sei?
Chii chinonzi gardama?
Gardama, anozivikanwawo seye mhasuru, mutema mutema kana Africa asparagus caterpillar, inogamuchira zita resainzi Spoptera exigua. Native kuAsia, ndechimwe chezvipembenene chinonyanya kukanganisa zvirimwa zvekurima, senge asparagus, bhinzi, pizi, bhiti, celery, kabichi, lettuce, mbatatisi, madomasi uye zviyo, pamwe nekuwanda kwezvishongo uye herbaceous marudzi.
Iyo yeblue kana grey moth inoyera 2 kusvika 3 masentimita. Izvi hazvikuvadzi zvachose kuzvirimwa, asi zvakakosha kuti uzviite kuitira kuti irege kuwana mukana wekuisa mazai ayo, nekuti maruva ayo ane njodzi huru. Aya akasvibira uye shava, ane mitsetse yenguva refu pazasi, uye dzinodya pamashizha nemaruva.
Unorwa sei?
Pane nzira mbiri dzekurwisa nayo:
Mushonga wezvakatipoteredza
Kana zvasvika kune zvirimwa zvekurima, chakanakira nguva dzose kushandisa zvigadzirwa zvakasikwa, senge Bacillus thuringiensis iyo iwe yauchawana iri kutengeswa munzvimbo dzekuchengetedza. Iyo bhakitiriya inobvisa maruva ezvipembenene, kusanganisira aya egardama.
Synthetic (kemikari) mushonga
Kana izvo zvaunazvo zvichikanganisa zvishongo zvekushongedza, unogona kushandisa makemikari zvipembenene. Mushonga unonyanya kushanda ndewunotevera:
- Bhagidhi remarita makumi matanhatu emvura rakazadzwa.
- Makirogiramu zana emubatanidzwa anowedzerwa.
- 1 kilo yeshuga inowedzerwa.
- Uye pakupedzisira, mazana manomwe emamirimita machubhu Chlorpyrifos akawedzerwa.
Ipapo, zvese zvakasanganiswa mushe uye chipfapfaidzo chinozadzwa kuti uzomwaya zvakapoteredza chirimwa nacho.
Tinovimba kuti ikozvino unogona kurwisa iyo gardama 🙂.
