تأثير مزج الزيت المعدني مع المبيدين الفطريين Flint, وTrifmine في بعض الصفات الإنتاجية للبندورة المحمية
Abstract
تم اختبار تأثير الزيت المعدني الصيفي ، ومزيجه بكل من مستحضري المبيدين الفطريين التجاريين Flint, وTrifmine ، في بعض الصفات الإنتاجية لمحصول البندورة في الزراعة المحمية في الساحل السوري, استعمل المبيدان المدروسان بالتركيزات الموصى بها, مع أو بدون مزج بالزيت المعدني, أظهرت النتائج عدم وجود تأثيرات سلبية معنوية لرش مزيج الزيت المعدني مع أيٍّ من المبيدين المدروسين في الإزهار, تشكل الثمار, عدد الثمار, ووزن الثمار؛ فقد تراوح متوسط عدد ثمار النبات بين 71.0 و75.0 ثمرة/النبات ، مقارنة بـ 67.8 ثمرة /النبات للشاهد ، وتراوح وزن الثمرة بين 75.3 – 87.2 غ/ثمرة في حال عدم مزج المبيدات مع الزيت, أما في حال المزج مع الزيت كان متوسط عدد ثمار النبات بين 69.1 - 76.4 ثمرة/النبات, ومتوسط وزن الثمرة 74.8–81.7 غ/ثمرة مقارنةً
بـ 62.6 غ/ثمرة في الشاهد, ولم تكن الفروق معنوية.
To evaluate the effects of summer mineral oil which were mixed with tow systemic commercial fungicides Flint and Trifmine on some tomato yield properties in Syrian coast greenhouse conditions, the tow fungicides were supplied at the recommended doses (mixed with mineral oil or not), the results showed no negative effctes on the plant flowers, fruits, fruit's weight through the study; there were 71.0-75.0 fruits on each plant and fruit's weight was 75.3-87.2 g/one fruit in treatments which fungicides were not mixed with mineral oil, 69.1-76.4 fruits on each plant, 74.8-81.2 g/one fruit in treatments which fungicides were mixed, compairing with 62.2 fruits/plant in control, 87.6 g/fruit in control, differences were not significant.
