Ithagethi yokuvimbela nokulawula

eMancozebisetshenziselwa ikakhulukazi ukuvimbela nokulawula imifino ye-downy mildew, i-anthracnose, isifo se-brown spot, njll. Njengamanje, iyi-ejenti efanelekile yokulawula ukubola kwangaphambi kwesikhathi kukatamatisi kanye nokulimaza kwamazambane sekwephuzile, okunomphumela wokulawula cishe u-80% no-90% ngokulandelana. Ivamise ukufuthwa emaqabunga, kanye njalo ezinsukwini eziyi-10 kuya kweziyi-15.

Ukulawula ukubola, i-anthracnose kanye nesifo samachashazi amaqabunga kutamatisi, ama-eggplant namazambane, sebenzisa u-80% wempushana omanzi ngokwesilinganiso izikhathi ezingama-400 kuya kwezingama-600. Fafaza ekuqaleni kwesifo, izikhathi ezi-3 kuya kwezi-5 zilandelana.

(2) Ukuze uvimbele futhi ulawule ukuwohloka kwezithombo kanye nokubola kwezithombo emifino, gcoba impushana emanzi engu-80% embewini ngesilinganiso esingu-0.1-0.5% wesisindo sembewu.

(3) Ukuze ulawule i-downy mildew, i-anthracnose kanye nesifo samabala ansundu kumakhabe, fafaza ngengxube ehlanjululwe izikhathi ezingu-400 kuya kwezingu-500 izikhathi ezi-3 kuya kwezi-5 zilandelana.

(4) Ukuze ulawule i-downy mildew eklabishini laseShayina kanye ne-kale kanye nesifo samabala kusilimo esidliwayo esinamagatsha anamanzi, fafaza ngesisombululo esihlanjululwe izikhathi ezingu-500 kuya kwezingu-600 izikhathi ezi-3 kuya kwezi-5 zilandelana.

(5) Ukuze ulawule i-anthracnose nesifo samachashazi abomvu kubhontshisi wezinso, fafaza ngesisombululo esihlanjululwe izikhathi ezingu-400 kuya kwezingu-700 izikhathi ezi-2 kuya kwezi-3 ezilandelanayo.

Ukusetshenziswa okuyinhloko

Lo mkhiqizo uwumuthi wokukhunta obanzi wokuvikela amaqabunga, osetshenziswa kakhulu ezihlahleni zezithelo, imifino kanye nezitshalo zasensimini. Ingakwazi ukulawula izifo ezihlukahlukene ezibalulekile zesikhunta samaqabunga, njengokugqwala kukakolweni, isifo samabala amakhulu embila, i-phytophthora blight emazambane, isifo se-black star ezihlahleni zezithelo, i-anthracnose, njll. Umthamo ngu-1.4-1.9kg (isithako esisebenzayo) ehektheleni. Ngenxa yobubanzi bayo bezicelo nokusebenza kahle kwayo, isibe yinhlobonhlobo ebalulekile phakathi kwama-fungicides avikelayo angewona amasistimu. Uma isetshenziswa ngokushintshana noma ixutshwa nama-systemic fungicides, ingaba nemiphumela ethile.

2. Isikhunta esivikelayo esibanzi. Isetshenziswa kakhulu ezihlahleni zezithelo, imifino kanye nezitshalo zasensimini, futhi ingavimbela futhi ilawule izifo eziningi ezibalulekile zesikhunta samaqabunga. Ukufafaza izikhathi ezingama-500 ukuya kwezingama-700 kuhlanjululwe ngo-70% wempushana emanzi kungalawula ukubola kwangaphambi kwesikhathi, isikhunta esimpunga, i-downy mildew kanye ne-anthracnose yamakhabe emifino. Ingasetshenziswa futhi ukuvimbela nokulawula isifo senkanyezi emnyama, isifo senkanyezi ebomvu, i-anthracnose nezinye izifo ezihlahleni zezithelo.
