Abstract Political efforts are made in the European Union (EU) to reduce pesticide use and increase implementation of integrated pest management (IPM). Within EU project ENDURE, research priorities on reduction defined. Using maize, one most important crops Europe, as a case study, we identified serious weeds, arthropod pests, fungal diseases well classes amounts pesticides applied. Data for 11 maize growing regions were collected from databases, publications expert estimates. Silage...
Increasing concerns about pesticide use and a steadily increasing conversion to organic farming have been major factors driving research in physical cultural weed control methods Europe. This article reviews some of the results achieved with nonchemical strategies, especially adapted for row crops (e.g., corn, sugar beet, onion, leek, carrot) small-grain cereals barley wheat). In crops, intrarow weeds constitute challenge, has mainly aimed at replacing laborious hand-weeding mechanization. A...
Summary Weed control within crop rows is one of the main problems in organic farming. For centuries, different weed removal tools have been used to reduce weeds rows. Stimulated by demand from farmers, research several European countries over last decade has focused on mechanisation using harrowing, torsion finger weeding and with compressed air (Pneumat). Intelligent weeders are now being developed which offer more advanced ways weeds, including larger ones leave plants unharmed. One first...
Summary Physical, cultural and biological methods for weed control have developed largely independently are often concerned with in different systems: physical annual crops biocontrol extensive grasslands. We discuss the strengths limitations of four control: mechanical, thermal, cutting, intercropping, advantages disadvantages combining them. These may increase soil nitrogen levels alter microclimate at level; this be benefit to agents, although disturbance plant damage detrimental. Some...
Noninversion tillage with tine- or disc-based cultivations prior to crop establishment is the most common way of reducing for arable cropping systems small grain cereals, oilseed rape, and maize in Europe. However, new regulations on pesticide use might hinder further expansion reduced-tillage systems. European agriculture asked become less dependent pesticides promote protection programs based integrated pest management (IPM) principles. Conventional noninversion rely entirely availability...
Crop management factors, such as tillage, rotation, and straw retention, need to be long-term allow conclusions on effects crop yields, nitrate leaching, carbon sequestration. In 2002, two field experiments, each including four cash rotations, were established soils with 9 15% clay, under temperate, coastal climate conditions. Direct drilling harrowing different depths compared plowing respect yield, N For comparison of yields across grain seed dry matter for converted equivalents (GE)....
Summary Infestation with Cirsium arvense in organic cropping is an increasing problem many parts of Europe. Non‐chemical management strategies against C. , based on cultivation tactics and/or different cutting regimes, have received very little attention for years. This study presents results from four experiments, undertaken under growing conditions, the effects repeated mowing or hoeing during first part season, used combination competition a suppressive crop (grass/white clover mixture...
Summary Apera spica‐venti is a winter annual grass and, increasingly, severe weed problem in autumn‐sown crops. Non‐inversion tillage has become more common Denmark recent years, but may accentuate problems with A. . These be avoided, if selected preventive and cultural management practices are adopted. To this end, we conducted 4‐year field study investigating the effects of crop rotation, method, location limited herbicide input on population dynamics yield. Additionally, detailed studies...
Manual weeding of intrarow weeds in direct‐sown leek and bulb onion crops grown organically can be very labour‐intensive. Four field experiments, two were made this investigation to study the effects physical cultural methods on weed numbers, time consumption for hand‐weeding marketable yield parameters. The considered were: pre‐emergence flaming harrowing, post‐emergence hoeing close row (only leek) vertical brush weeding. seed priming, slurry placement cultivar choice leek). Generally,...
Summary Steaming the soil prior to crop establishment can be a very effective method of preventing weed seedling emergence on raised beds vegetable crops. However, current mobile steaming technology for outdoor vegetables is characterized by an extremely high energy consumption and low work rate. This has led concept band‐steaming, where only limited volume steamed corresponding intrarow area row‐grown crop. Weeds growing in are difficult remove traditional non‐chemical means, usually...

Soil steaming applied in bands is a new technology with the potential to radically lower burden of hand-weeding intra-row weeds non-herbicidal vegetable cropping. Preliminary studies band-steaming have shown effective control viable weed seeds when maximum soil temperatures reach 60–80°C. This temperature range has particular agronomic interest, and present study aimed at investigating influence factors heat duration on seed mortality targeting Two types (sand versus sandy loam) two moisture...
