| چکیده | ||
| امروزه نیاز مبرمی به بررسی سرعت کاهش و تخریب آفتکشها پس از کاربرد در مزارع و ارزیابی فاصله ایمن قبل از برداشت برای اطمینان از ایمن بودن بقایای باقیمانده آفتکشها در محصول وجود دارد. در این مطالعات سینتیک تخریب و کاهش قارچکشهای دیفنوکونازول + فلوکساپیروکساد )داگونیس®( با فرمولاسیون سوسپانسیون غلیظ ((SC 7.5/5 که برای کنترل بیماری سفیدک پودری گوجهفرنگی استفاده میشوند و همچنین قارچکشهای دیمتومورف + سیموکسانیل WG 70% (پیلارکسانیل®) که برای کنترل بیماری سفیدک کرکی خیار بکار میروند مورد بررسی قرار گرفتهاند. دوره پیش برداشت (کارنس) این آفتکشها در محصولات خیار و گوجهفرنگی سه روز برآورد شده است که با بررسی سینتیک زوال و کاهش آنها در محصولات خیار و گوجهفرنگی گلخانهای این موضوع در دوزهای بهینه و بیشینه مورد بررسی قرار گرفت. پایش مقادیر باقیمانده بلافاصله پس از سمپاشی تا یازده روز بعد از آن با سه بار تکرار انجام شد. مقادیر باقیمانده با توجه به MRLهای ملی این قارچکشها ارزیابی شد که برای همه آنها در همه زمانهای نمونه برداری، مقادیر باقیمانده کمتر از MRL ملی بود. بنابراین، دوره پیش برداشت 3 روزه برای هر دو قارچکش داگونیس و پیلارکسانیل قابل قبول میباشد. معادلات سینتیک مرتبه اول برای آفتکشهای مورد مطالعه نیز تایید کننده دوره پیش برداشت سه روز میباشد. | ||

| Today, there is an urgent need to investigate the rate of reduction and degradation of pesticides after application in the field settings and to assess the safe pre-harvest intervals to ensure that pesticide residues in the crop are safe. In this study, the degradation and reduction kinetics of difenoconazole + fluxapyroxad as a combined suspension concentrate (SC 7.5/5 (Dagonis®) used to control powdery mildew on tomatoes were examined, as well as the fungicides dimethomorph + cymoxanil as a water dispersible granule (WG 70% (Pilarexanil®) used to control internal powdery mildew on cucumbers. The pre-harvest interval (PHI) of these pesticides in cucumber and tomato crops was estimated to be 3 days, derived from kinetic analyses of degradation and reduction under greenhouse conditions at both optimum and maximum rates. Monitoring of residues was conducted immediately after spraying and continued for 11 days, with three replicates. Residue levels were evaluated according to the national MRLs of these fungicides, and at all sampling times, the residues remined below the national MRLs. Consequently, the PHI of 3 days for both Dagonis® and Pilarexanil® is deemed acceptable. First-order kinetic analyses of the pesticides studied also support the 3-day PHI. | ||
