IMancozeb

Injongo yokuthintela nokulawula

IMancozebIsetyenziswa kakhulu ekuthinteleni nasekulawuleni i-vegetable downy mildew, i-anthracnose, isifo samabala amdaka, njl. Okwangoku, sisixhobo esifanelekileyo sokulawula ukubola kwasekuqaleni kweetamatato kunye nokubola kwasemva kwexesha kweetapile, kunye nemiphumo yokulawula malunga ne-80% kunye ne-90% ngokulandelelana. Ihlala itshizwa emagqabini, kanye emva kweentsuku ezili-10 ukuya kwezili-15.

Ukulawula i-blight, i-anthracnose kunye nesifo samachaphaza amagqabi kwiitumato, ii-eggplant kunye neetapile, sebenzisa i-80% yomgubo omanzi ngomlinganiselo wezihlandlo ezingama-400 ukuya kuma-600. Futha kwisigaba sokuqala sesifo, izihlandlo ezi-3 ukuya kwezi-5 zilandelelana.

(2) Ukuthintela nokulawula ukufuma kwezithole kunye nomonakalo wezithole kwimifuno, galela i-80% yomgubo omanzi kwimbewu ngesantya se-0.1-0.5% yobunzima bembewu.

(3) Ukulawula i-downy mildew, i-anthracnose kunye nesifo samabala amdaka kwiivatala, fafaza ngesisombululo esixutywe kayi-400 ukuya kuma-500 izihlandlo ezi-3 ukuya kwezi-5 ezilandelelanayo.

(4) Ukulawula i-downy mildew kwikhaphetshu yaseTshayina kunye ne-kale kunye nesifo samabala kwiseleri, fafaza ngesisombululo esixutywe ngamanzi ngokuphindwe ka-500 ukuya kuma-600 amaxesha amathathu ukuya kwamahlanu alandelelanayo.

(5) Ukulawula i-anthracnose kunye nesifo samabala abomvu kwiimbotyi zezintso, fafaza ngesisombululo esixutywe ngamanzi ngokuphindwe ka-400 ukuya ku-700 amaxesha ama-2 ukuya kwama-3 alandelelanayo.

Iindlela eziphambili zokusetyenziswa

Le mveliso yi-broad-spectrum fungicide yokukhusela amagqabi, esetyenziswa kakhulu kwimithi yeziqhamo, imifuno kunye nezityalo zasemasimini. Ingalawula iintlobo ngeentlobo zezifo ezibalulekileyo zefungus zamagqabi, ezifana nokugqwala kwingqolowa, isifo sebala elikhulu embona, i-phytophthora blight kwiitapile, isifo se-black star kwimithi yeziqhamo, i-anthracnose, njl. Umlinganiselo yi-1.4-1.9kg (isithako esisebenzayo) kwihektare nganye. Ngenxa yoluhlu olubanzi lwezicelo kunye nokusebenza kakuhle, iye yaba ludidi olubalulekileyo phakathi kwe-non-systemic protective fungicides. Xa isetyenziswa ngokutshintshana okanye ixutywe ne-systemic fungicides, inokuba nemiphumo ethile.

2. I-fungicide ekhuselayo ene-broad-spectrum. Isetyenziswa kakhulu kwimithi yeziqhamo, imifuno kunye nezityalo zasemasimini, kwaye inokuthintela kwaye ilawule izifo ezininzi ezibalulekileyo zefungus zamagqabi. Ukutshiza i-70% yepowder emanzi exutywe izihlandlo ezingama-500 ukuya kwezingama-700 kunokulawula ukubola kwangoko, ukungunda okungwevu, ukungunda okuphantsi kunye ne-anthracnose yeevatala kwimifuno. Ingasetyenziselwa ukuthintela nokulawula isifo se-black star, isifo se-red star, i-anthracnose kunye nezinye izifo kwimithi yeziqhamo.
