Biochemical Studies on the Effect of Insecticides and herbicides on sugar beet
Safaa Salem Mohamed El- sayed;
Abstract
A field experiment was carried out in Sakha research station (Kafre. EL- Shiekh Governorate )
i during the growing season of (19 ,9-2000) in order to study the relative effect of some insecticides ( Lannate , Actellic) and herbicides ( Goltix, Fusilade ) on growth criteria ,
' biochemical constituents , yield and its attributes of sugar beet plant . Each of the insecticides and herbicides were used by the n commended dose, Goltix ( 2Kg /fed.) Fusilade (1Y:. L!fed. ) , Lannate (300 g/fed.) and Actellic (I Y:. L!fed.). The results could be summarized as the following :
• The results showed that treatment of (Goltix+Fusilade ) attained the highest values of chlorophyll (b) and reducin1 sugar percentage of sugar beet leaves (LRS%) and invertase activity in sugar beet roots at the two growth stages.
• The interaction between the insecticide Actellic and treatment of herbicides (Goltix and Fusilade) gave the highest values of chlorophyll (a) by 10.87 and 6.59 mg /g. fresh weight at (120, 210) from planting, invertase enzyme activity by 3.37 mg glucose /30 min I gm.f.w of sugar beet leaves at 120 days and sucrose percentage by 15.02% and 17.95% of
sugar beet roots at 120, 2' 0 days respectively.
• Neither insecticide nor herb cide treatments gave a significant influence on the values of top and roots yield .
• The obtained results showed that the highest juice purity ( 82.5%) and sugar yield ( 6.11 ton 1 fed) were produced w1en the sugar beet plant treated by the interaction between Lannate insecticide and thEherbicides ( Goltix + Fusilade) at harvest.
