Assessing the potentialities of innovating cropping systems to reduce pesticide losses to groundwater through a network of long term experimental sites and quantitative modelling
EAGESTADAGROSUP; Assessing the potentialities of innovating cropping systems to reduce pesticide losses to groundwater through a network of long term experimental sites and quantitative modelling. 5. International Ecosummit “Ecological Sustainability : Engineering Change”
Modelling the fate of pesticides in innovative cropping systems disigned to reduce the use of pesticides
EAAgroSupINRAGESTAD; The objective of this work was to assess and compare the ability of three pesticide fate models (MACRO, PEARL and PRZM) to simulate the concentration in leachates of pesticides applied in different conventional and innovative cropping systems. The test of the models was based on measurements of water flows and pesticides concentrations done in two French experimental sites. The results showed that MACRO was the most efficient model to simulate the amounts of percolated water and the concentrations of pesticides used in the various cropping systems
Assessing human health risks from pesticide use in conventional and innovative cropping systems with the BROWSE model
Background: Reducing the risks and impacts of pesticide use on human health and on the environment is one of the objectives of the European Commission Directive 2009/128/EC in the quest for a sustainable use of pesticides. This Directive, developed through European national plans such as Ecophyto plan in France, promotes the introduction of innovative cropping systems relying, for example, on integrated pest management. Risk assessment for human health of the overall pesticide use in these innovative systems is required before the introduction of those systems to avoid that an innovation becomes a new problem. Objectives: The objectives of this work were to assess and to compare (1) the hum…
Maize-based low-input cropping systems can provide effective weed control while ensuring crop productivity
Conventional Maize Monoculture (MMConv) is now questioned for environmental reasons. During a five-year field experiment, yield and weed pressure of MMConv was compared to three low-input Cropping Systems (CS) : MMLI, a Low-Input Maize Monoculture; MMCT, a Conservation Tillage Maize Monoculture; Maize-MSW, Maize rotated with Soyabean and Wheat, all designed to reduce water pollution. In 2014 and 2015, weed-free zones were established on all CS. Weed biomass was higher in MMCT, especially for spring grasses and perennials. MMConv (11.3±1.1 T ha-1) and MMLI (10.6±2.3 T ha-1) had higher grain yields than MMCT (8.2±1.9 T ha-1). Finally, concerning yields observed in weed-free zones, MMCT yields…
