Abstract

O‘zbekistonda kartoshkaning virus kasaliklari keng tarqalgan va ular ekin hosildorligi va urugʼlik sifatlarini pasaytiradi. Viruslar keltiradigan zarar miqdori esa ekinning nafaqat urugʼlik sifatlarini, balki hosildorlikning pasayishiga ham olib kelishi bilan xarakterlanadi. Bu zarar o‘simlikdagi fiziologik jarayonlarning buzilishi natijada ularning o‘sishi va rivojlanishidagi anomal holatlarga olib kelishi tufayli sodir bo‘ladi. Bunday taʼsir esa o‘simliklarning mahsuldorligida aks etadi. Kartoshkaning Farovon navining elita maydonlarida viruslardan sogʼlom o‘simliklarning mahsuldorligi har bir tupdan o‘rtacha 620 grammni, X-virusi bilan zararlangan o‘simliklarda esa 550 grammni tashkil qildi. Har bir o‘simlikda shakllangan tuganaklar soni muvofiq ravishda 9 va 7,8 donani tashkil qilib, X virusi taʼsirida har bir o‘simlikda shakllanadigan tuganaklar soni o‘rtacha 1,2 donaga kamaydi. Farovon navida o‘simliklarning X virusi bilan yashirin shaklda zararlanishi mahsuldorlikni 13,9% pasaytiradi. Mahsuldorlikning pasayishi tuganaklar sonining va massasini kamayishi hisobiga kuzatiladi. Shuning uchun kartoshka urugʼchiligida nafaqat yaqqol shakldagi, balki yashirin shakldagi zararlanishini oldini olishga qaratilgan tadbirlarni qo‘llash lozim.
