چکیده

فرمولاسیون های EC به‌واسطه داشتن حلال­ های سمی مانند زایلین خطر زیست‌محیطی داشته و نانوفرمولاسیون‌های ایمن‌تر و مؤثرتر می­توانند در توسعه روش­ های نوین مدیریت کنترل آفات مفید واقع شوند. در این تحقیق نانوفرمولاسیون دلتامترین 5/2 درصد تهیه، اندازه، شکل و میزان ماده مؤثره  آن با استفاده از روش‌های SEM، AFM، DLS و TGA تأیید شد. سپس این نانوفرمولاسیون برای کنترل سن گندم در مراحل سن بالغ زمستان‌گذران، پوره سن چهارم و سن نسل جدید با آفت‌کش تجاری مقایسه شد. تیمارها شامل نانوفرمولاسیون دلتامترین، نانوحامل، دلتامترین EC2.5% و آب به‌عنوان شاهد بود. نانوفرمولاسیون اثر حشره‌کشی خود را در شرایط آزمایشگاهی، بعد از 45 روز به‌خوبی(73‌ درصد) حفظ کرد ، اما میزان تلفات در فرمولاسیون تجاری EC بسیار پایین (13‌ درصد) بود. در ارزیابی‌های گلخانه‌ای، این فرمولاسیون در غلظت 125 میلی‌گرم بر لیتر، تلفات بالای 90‌ درصد علیه سن بالغ زمستان‌گذران داشت و در 45 روز پس از سم‌پاشی نیز تلفات پوره به 40‌ درصد کاهش یافت.

چکیده [English]

Most EC formulations contain toxic solvents such as xylene that have environmental and carcinogenic risks, using more effective nanoformulations can be effective in developing healthy and safe methods in managing pests.The nanoformulation of 2.5% deltamethrin was prepared and the size, shape, and amount of active ingredient were investigated using SEM, AFM, DLS, and TGA methods. This nanoformulation was compared with commercial pesticides to control Sunn-pest in the stages of overwintered adults, 4th instar nymphs, and new generation adults. The treatments included nanoformulation, nanocarrier, commercial EC2.5%, and water as control. The results showed that this nanoformulation has improved ingredient efficiency. The insecticidal effect was well preserved in 45 days after spraying (73%), but the effect of commercial EC formulation was reduced and the mortality rate was very low (13%). Evaluation of treatments in greenhouse conditions showed that both formulations at a concentration of 125 mg.L had a percentage of mortality above 90% compared to the overwintering adults and in 45 days after spraying the percentage of 4th instar nymphs mortality was reduced to 40%.
