The residual effect of malathion (organophosphate)‎ and sevin (carbamate)‎ application on sugar beet (chenpodiaceae)‎ growth

Abstract EN

An experiment was conducted at Shambat Agricultural Farm to Study the effect of pesticides residues on soil and plant.

Beet Root was planted on January, 2007 and Sevin, Malathion pesticides were added to evaluate weight, length, area and number of leaves per plant.

The results revealed that Sevin pesticide at the recommended dose (1.9 kg/ha) gave positive effect on height, weight, leaf area, and number of leaves per plant.

The average plant height was 52.3 cm compared with 47.0 cm for the check.

The weight average was 493 gm in comparison with control (480 gm).

The average number of leaves was 18 compared to 16 for the check.

The leaf area was 58.4 cm² compared to 53.2 cm² .

The increased dose of 2.85 kg/ha of Sevin decreased all the parameters.

The same trend was observed with Malathion pesticide.-
