Although blossom end rot looks like a disease, it is actually a ‘physiological disorder’ or general plant problem, caused by incorrect growing conditions.
Blossom end rot is a common problem of tomatoes, peppers and aubergines – especially those grown in a greenhouse – and is caused by erratic watering and/or excessive dryness at the roots. It is often a common problem of plants grown in growing-bags that are not watered properly.
Brown, sunken spots develop at the bottom of the fruit opposite the stem.
Treatment and control
Ensure the compost is kept evenly moist and not allowed to dry out. Giant planters contain twice as much compost as ordinary growing-bags, so are less likely to dry out between waterings.
Pick off affected fruit and change your watering technique to applying less water twice a day, rather than an occasional flood followed by drying out.
Feed every week with a soluble tomato food, since a lack of nutrients also adds to the problem.
Ingawa kuoza kwa mwisho wa maua huonekana kama ugonjwa, kwa kweli ni "ugonjwa wa kisaikolojia" au tatizo la jumla la mmea, linalosababishwa na hali zisizo sahihi za kukua. Uharibifu wa mwisho wa maua ni tatizo la kawaida la nyanya, pilipili na aubergines - hasa wale waliolimwa katika chafu - na husababishwa na umwagiliaji usio wa kawaida na / au ukame wa kupita kiasi kwenye mizizi. Mara nyingi ni tatizo la kawaida la mimea inayokua katika mifuko ya kukuza ambayo hainywi maji vizuri. Sehemu za rangi ya kahawia, zilizozama, hutokea chini ya tunda lililo kinyume cha shina. Matibabu na udhibiti Hakikisha kwamba mbolea huhifadhiwa kwa unyevu sawa na hairuhusiwi kukauka. Vipande vikubwa vya mimea vina mbolea mara mbili kuliko mifuko ya kawaida ya kukuza, kwa hiyo ni rahisi zaidi kukauka kati ya kunyunyizia maji. Chukua matunda yaliyoathiriwa na ubadilishe mbinu yako ya kunyunyizia maji kwa kutumia maji machache mara mbili kwa siku, badala ya mafuriko ya mara kwa mara yanayofuatwa na kukauka. Kila wiki, kula chakula cha nyanya, kwa kuwa ukosefu wa virutubisho pia huongeza tatizo.
