Mazkur tadqiqotda nok (Pyrus communis L.) bo‘g‘larining Xlorokis Medi (689,5 g/kg) va Simoksanil (42 g/kg) preparatlari bilan ishlov berilishi vegetativ rivojlanish, gullash va urug‘lanish samaradorligiga ta’siri o‘rganildi. Eksperiment 4–6 yoshli daraxtlar ustida olib borildi. Tadqiqot natijalari shuni ko‘rsatdiki, preparat bilan ishlov berilgan bo‘g‘lar yangi barglar va filiallar soni, bo‘g‘ uzunligi va poya qalinligi jihatidan sezilarli o‘sish ko‘rsatdi. Xlorokis Medi bilan ishlov berilgan bo‘g‘lar eng yuqori vegetativ rivojlanish ko‘rsatkichlarini namoyon etdi. Shuningdek, preparat qo‘llangan daraxtlarning gullari nazorat guruhiga nisbatan 15% ko‘proq urug‘landi, meva urug‘lari soni ko‘paydi va meva sifati yaxshilandi. Natijalar kimyoviy preparatlarning vegetativ va generativ jarayonlarga ijobiy ta’sir ko‘rsatishini hamda meva hosilini oshirishda samarali vosita ekanligini tasdiqlaydi. Tadqiqot natijalari mevali bog‘larda preparatlarni ishlatishning amaliy ahamiyatini ko‘rsatadi va kelgusida preparatlarning samaradorligini turli iqlim sharoitlarida va turli yoshdagi daraxtlarda o‘rganishga asos yaratadi.
