Lesi sithombe sendawo esinekhwalithi ephezulu sithwebula umbono oseduze wezitshalo ezine ze-lettuce embhedeni wengadi, ngasinye sibonisa izimpawu ezihlukile zezifo ezivamile zomzimba neze-pathological. Inhlabathi insundu ngokumnyama, imanzi kancane, futhi inombala onama-organic debris kanye nama-clump amancane, okunikeza isizinda semvelo sendawo yokuxilonga.
Kusukela kwesobunxele kuya kwesokudla, isitshalo sokuqala se-lettuce sibonisa izimpawu ze-downy mildew. Amaqabunga aso angaphandle aluhlaza okotshani okukhanyayo anamabala aphuzi angajwayelekile kanye nokukhula okumpunga okufiphele ngaphansi, okubonisa ukutheleleka kwesikhunta. Amaqabunga athintekile ayabuna futhi agobile, kuyilapho amaqabunga angaphakathi egcina umbala oluhlaza okotshani omnyama futhi abonakala enempilo. Isisekelo sesiqu sijiyile futhi simhlophe, sibonakala kancane ngaphezu kwenhlabathi.
Isitshalo sesibili, esibekwe phakathi nendawo, sibonisa izimpawu zokubola kwangaphansi. Amaqabunga angaphandle onakele kakhulu, anezicubu ezinsundu ezimnyama, ezifile ezigxile eduze kwesisekelo lapho amaqabunga ehlangana khona nomhlabathi. Lawa maqabunga agobile ngaphakathi futhi abola, eveza umongo obolile. Amaqabunga angaphakathi aseluhlaza kodwa abonisa izimpawu zokuqala zokugoba nokucindezeleka. Inhlabathi ezungezile iphazamiseke kancane, inezingcezu nezingcezu ezisakazeke nxazonke zesitshalo.
Isitshalo sesithathu se-lettuce yi-bolting, ebonakala ngesiqu eside, esiqondile esiphakathi esiphuma ku-rosette. Lesi siqu simbozwe ngamaqabunga aqinile aluhlaza okotshani akhuphukayo aba mancane kancane ngokuya esicongweni. Amaqabunga angaphandle makhulu, ashwabene, futhi axubene nohlaza okotshani olukhanyayo nolumnyama, olunesikhumba esincane. Isiqu se-bolting siqinile futhi siqinile, okubonisa ukushintsha kwesitshalo kusuka ekukhuleni kwezitshalo kuya ekukhuleni kokuzala.
Isitshalo sesine, esitholakala ekhoneni elingezansi kwesokudla, sibonisa ukusha kwezihloko. Amaqabunga aso abanzi futhi aluhlaza okotshani, anemiphetho ensundu emnyama, eyomile, neqhoqhoqho. Umonakalo unzima kakhulu emaqabungeni angaphandle, kuyilapho amaqabunga angaphakathi ehlala eluhlaza kakhulu futhi enombala onsundu omncane eziqongweni. Isitshalo siphansi emhlabathini, namaqabunga avuleke ngaphandle ngendlela eqondile.
Isithombe sigxile kakhulu, sembula imininingwane emincane njengokuthungwa kwamaqabunga, izilonda zezifo, kanye nobuningi bomhlabathi. Ukukhanya kungokwemvelo futhi kuyalingana, kuthuthukisa ukubonakala kwesibonakaliso ngasinye ngaphandle kwezithunzi ezinzima. Ukwakheka kuyafundisa futhi kuyaxilonga, kulungele ukubonisa izifo ze-lettuce ekuqeqeshweni kwezolimo, iziqondiso zezempilo zezitshalo, noma izinsiza zokuphathwa kwezitshalo.
