Residual levels of imazamox herbicide and derivatives in different parts of sunflower plant and honey samples produced under the effect of sunflower flora

Abstract

This research was carried out under flowerpot conditions in Kırklareli province of Thrace region. The pots were filled with two different soil types, which had loamy sand and sand structures. The imazamox with the doses of 0.5 and 7.5 ml da^-1 were applied to the sunflower plant when it had 4-10 leaves. The study was carried out in watery conditions and the irrigations were done three different phenological periods. Imazamox residual amounts were determined in leaf, stem and table parts of the sunflower plant in the study. Besides, the honey samples, which were produced under the effect of sunlower flora, were collected from different regions and it was investigated whether or not the imazamox herbicide left residual in the final products. According to the results, the imazamox residual amount levels in different parts of the plant were ranged as table>leaf>stem. Imazapic and imazapyr derivatives in the leaf part and imazapic derivatives in the stem part were observed. Different amounts of imazamox doses, irrigation ratios and the soil structure were effective on the residual amounts. The residuals of imazamox and derivatives in the honey samples were not observed.

İmazamox herbisitinin ve türevlerinin ayçiçeği bitkisinin farklı aksamlarında ve ayçiçeği florası etkisi altında üretilen bal örneklerindeki kalıntı düzeyleri

Abstract

Araştırma Trakya Bölgesi/Kırklareli İlinde saksı koşullarında yürütülmüştür. Saksılar tınlı kum ve tın bünyeye sahip iki farklı toprak ile doldurulmuştur. Ayçiçeği bitkisine 4-10 gerçek yapraklı olduğunda 0.5 ve 7.5 ml da^-1 dozlarında imazamox uygulanmıştır. Çalışma sulu şartlarda yürütülmüş olup, sulamalar tabla oluşumu, çiçeklenme başlangıcı ve süt olumu fenolojik dönemlerinde yapılmıştır. Çalışmada ayçiçeği bitkisinin yaprak, gövde ve tabla aksamlarındaki imazamox kalıntı miktarları belirlenmiştir. Ayrıca farklı bölgelerden, ayçiçeği florası etkisi altında üretilen bal örnekleri toplanarak, imazamox etkili maddesinin (herbisit) nihai ürünlerde kalıntı bırakıp bırakmadığı araştırılmıştır. Elde edilen sonuçlara göre; bitkinin farklı aksamlarında belirlenen imazamox kalıntı miktarları seviyeleri tabla>yaprak≥gövde (sap) olarak sıralanmıştır. Yaprak aksamında imazapic ve imazapyr, gövde aksamında da imazapic türevlerine rastlanmıştır. Uygulanan farklı miktarlardaki imazamox dozları, sulama oranları ve toprak yapısı, kalıntı miktarları üzerinde etkili olmuştur. Bal örneklerinde imazamox ve türevlerine ait kalıntılarına rastlanmamıştır.
