MAXIMIZE THE EFFECTIVENESS OF HERBICIDES RESISTANCE INJECTED THROUGH MODERN PRESSURIZED IRRIGATION SYSTEMS

Abstract

A field experiment was conducted at the experimental farm of Soils Department, at Faculty of Agriculture, Ain Shams University, Kaliubeya Governorate, Egypt, to maximize the effectiveness of herbicides resistance injected through modern pressurized irrigation systems. Two application techniques were used to weed control. Pre-emergence Pendimethalin herbicide (Stomp 50% EC) was applied via drip irrigation systems (surface & sub-surface) and conventional spraying by using knapsack sprayer with three concentration of the herbicide dosage rate recommended (100%, 75% and 50%) and control with treatment. Treatments have been conducted on green beans crop (Poulista variety) during the season (2018), to achieve the following Objectives: 1. Using the modern pressurized irrigation systems for weed control and maximize the benefit of herbicides. 2. Evaluate the effective of herbigation and spraying technique. 3. Increase the productivity with lower costs. 4. Obtaining an export product with high quality free from herbicides residues. The field experiment included: 1- Using drip irrigation system (surface & sub-surface) for weed control by herbigation technique. 2- Pre-emergence Pendimethalin herbicide (Stomp 50% EC) was applied via herbigation and conventional spraying technique. 3- Venturi device was used as injector for a herbicide and fertilizers for the season 4- Green beans crop (Poulista variety) during the season (2018).
