Ukusetshenziswa okuyinhloko

Lo mkhiqizo uyi-fungicide ebanzi yokuvikela amaqabunga, esetshenziswa kakhulu ezihlahleni zezithelo, imifino kanye nezitshalo zasensimini. Ungalawula izinhlobo ezahlukene zezifo ezibalulekile ze-fungi zamaqabunga, njengokugqwala kukolweni, isifo samabala amakhulu emmbileni, i-phytophthora blight kumazambane, isifo se-black star ezihlahleni zezithelo, i-anthracnose, njll. Umthamo u-1.4-1.9kg (isithako esisebenzayo) ngehektha ngalinye.

Sisetshenziswa kabanzi ezihlahleni zezithelo, imifino kanye nezitshalo zasensimini, futhi singavimbela futhi silawule izifo eziningi ezibalulekile zesikhunta zamaqabunga. Ukufutha impuphu emanzi ehlanjululwe izikhathi ezingu-500 kuya kwezingu-700 engu-700% kungalawula ukubola kwasekuqaleni, isikhunta esimpunga, isikhunta esiphansi kanye ne-anthracnose yamakhabe emifino.
