1. Kurandura no kurekura ubutaka
Kwirinda ibura ry'ibyatsi nigice cyingenzi mu micungire yubusitani bwicyayi mugihe cyizuba. Abahinzi b'icyayi bazakoreshaimashini yo guca nyakatsigucukura amabuye, urumamfu n'ibyatsi muri cm 10 z'umurongo utonyanga wa kanopi na cm 20 z'umurongo utonyanga, hanyuma ukoresheimashini izungurukakumena ubutaka bwuzuye, kurekura ubutaka, kubuhindura umwuka no gutembera, kunoza ubushobozi bwo kubika no gutanga amazi nifumbire, kwihutisha imikurire yubutaka, gukora igorofa ryoroshye kandi ryera cyane, guteza imbere imikurire yicyayi hakiri kare, no kongera icyayi umusaruro mu cyi no mu gihe cyizuba.
2. Kurwanya ifumbire mvaruganda
Nyuma yo gutora icyayi cyimpeshyi, intungamubiri mumubiri wigiti ziribwa cyane, imishitsi mishya ireka gukura, kandi sisitemu yumuzi ikomera, bityo rero ni ngombwa gufumbira mugihe kugirango hongerwe intungamubiri mumubiri wigiti. Ifumbire mvaruganda nka keke y'imboga, ifumbire, ifumbire mvaruganda, ifumbire y'icyatsi, nibindi, cyangwa nkifumbire mvaruganda buri mwaka cyangwa indi mwaka, irashobora gukoreshwa mumirongo isimburana, hanyuma igahuzwa nifumbire ya fosifore na potasiyumu. Mu gufumbira mu busitani bwicyayi, inshuro zo kwambara hejuru birashobora kuba byinshi muburyo bukwiye, kugirango igabanywa rya azote iboneka mu butaka iringaniye, kandi intungamubiri nyinshi zishobora kwinjizwa kuri buri mpinga y’ikura, kugirango umusaruro wiyongere buri mwaka .
3. Gerageza ikamba
Gutema ibiti byicyayi mubusitani bwicyayi butanga umusaruro mubisanzwe bifata gusa gutema byoroheje no gutema byimbitse. Gutema cyane bikoreshwa cyane mubiti byicyayi amashami yikamba afite ubucucike bukabije, kandi hariho amashami yinzara yinkoko n'amashami yapfuye, umubare munini wibibabi bifata, kandi umusaruro wicyayi ugabanuka kuburyo bugaragara. Ibiti by'icyayi birashobora gutemwa byoroshye naImashini yo gukata icyayi. Ubujyakuzimu bwo gutema byimbitse ni ugukata cm 10-15 z'amashami hejuru yikamba. Gutema cyane bigira ingaruka runaka ku musaruro wumwaka, kandi muri rusange bikorwa buri myaka 5-7 nyuma yigiti cyicyayi gitangiye gusaza. Gukata byoroheje ni ugukata amashami asohoka hejuru yikamba, muri rusange cm 3-5.
4. Irinde udukoko n'indwara
Mu busitani bw'icyayi mu cyi, ingingo y'ingenzi ni ukurinda no kurwanya indwara y'icyayi n'icyayi. Ibyibasiwe n’udukoko twangiza ni icyayi caterpillar hamwe nicyayi. Kurwanya udukoko birashobora kugenzurwa no kurwanya umubiri no kurwanya imiti. Kugenzura umubiri birashobora gukoreshaudukoko ibikoresho byo gufata. Imiti ni ugukoresha ibiyobyabwenge, ariko bigira ingaruka nke kumiterere yicyayi. Indwara ya cake icyayi yangiza cyane amashami mashya namababi akiri mato. Igisebe cyarohamye imbere yikibabi kandi kigasohoka kimeze nkumugati uhumeka inyuma, kandi gitanga intanga ngabo zera. Mu gukumira no kuvura, irashobora guterwa 0.2% -0.5% yumuringa wa sulfate wumuringa, ugaterwa rimwe muminsi 7, hanyuma ugaterwa inshuro 2-3 zikurikiranye. Amababi arwaye yatewe nicyayi cyicyayi aragoretse, adasanzwe kandi arashya, kandi ibikomere ni umukara cyangwa umukara wijimye. Mubisanzwe biboneka kumababi akiri yicyayi. Garama 75-100 za 70% thiophanate-methyl irashobora gukoreshwa kuri mu, ikavangwa na kg 50 yamazi hanyuma igaterwa buri minsi 7.
