Glyphosate Use in Forest Plantations
Under Chilean conditions the lack of weed control at forest tree establishment results in an average of at least 60% less biomass accumulation during the first year of growth of radiate pine or eucaliptus, and glyphosate ...
Using penoxsulam ALS inhibitor as a broad-spectrum herbicide in Chilean rice
The continuously-flooded rice production system in Chile has selected highly competitive aquatic weeds selection capable ofreducing paddy yields by 25 to 50%. Penoxsulam is a broad-spectrum triazolopyrimidine (ALS inhibitor) ...
Adsorption and desorption variability of four herbicides used in paddy rice production
This investigation was performed to determine the effect of physicochemical soil properties on penoxsulam, molinate, bentazon, and MCPA adsorption-desorption processes. Four soils from Melozal (35° 43' S; 71° 41' W), Parral ...
Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching
Once pesticides reach the soil, there are several factors that affect their soil behavior. To identify the principal soil and herbicide properties that control their adsorption and leaching, a study of five Chilean ...
Simazine transport in undisturbed soils from a vineyard at the Casablanca valley, Chile
Simazine is a soil-active herbicide that has been applied worldwide in agricultural soils, being the second most commonly detected herbicide in groundwater and surface waters. Although its use has been restricted in many ...
Water and sediment dynamics of penoxsulam and molinate in paddy fields: field and lysimeter studies
BACKGROUND: In Chile, rice is cultivated under water-seeded and continuously flooded conditions. Because herbicide dynamics in paddy fields and non-flooded fields is different, 3 year experiments were performed to study ...
