| • Lower accumulation of copper in the soil. • Less damage to microorganisms in the soil. • Potential saving in costs of spraying agent. • Improved distribution of spraying agent over the required period of treatment until exhaustion of the permitted maximum quantity. Practical recommendation Adapting dosage to state of infestation: As long as there is no infestation in a radius of 50 km, refrain from treating. Observe national information and alert services. As soon as the first case of infestation in the region is reported, protect potatoes with 200 to 250 g of pure copper per hectare. If potatoes in your own or neighbouring fields are afflicted by leaf blight, increase the dosage to 800 g and do not wait longer than a week in between treatments.... |

| • Perennial grass-clover leys promote wireworms. For this reason, a perennial cultivation of grass-clover ley should be avoided if there is any indication of wireworm infestation. • After ploughing the meadows or the perennial grass-clover ley, wait until the third or, if possible, even fourth year to plant susceptible crops like potatoes, carrots, onions or salad. • In general, a diverse crop rotation promotes various beneficial organisms and lowers the infestation of wireworms. • No cultivation of potatoes in strongly affected areas! • Rye, fodder radish and vetch are a possible green manure for overwintering. A low infestation of wireworms was observed in crop rotations with peas and lupines. • The cultivation of legumes (peas, field beans, bush... |

| Im Projekt «Mit Vielfalt punkten – Bauern beleben die Natur» (MVP) war das Jahr 2015 von Feldarbeiten geprägt. Zum letzten Mal wurden auf 47 Betrieben ökologische Daten erhoben. Es waren die gleichen Betriebe die schon 2009 und 2012 besucht wurden, und von denen die Hälfte im ersten Jahr ökologisch beraten wurde. Die Kontrolle und Verarbeitung der Felddaten zum Vorkommen von Pflanzen, Heuschrecken, Tagfaltern, Vögeln und Lebensräumen ist zurzeit im vollen Gange. Die Auswertungen im kommenden Jahr werden zeigen, ob sich die ökologische Beratung und die von den Landwirten in der Zwischenzeit umgesetzten Massnahmen messbar positiv auf die Biodiversität ausgewirkt haben. Im Projekt-Teil «Sozio-Ökonomie» wurden 16 Landwirtinnen und Landwirte erneut interviewt.... |

| Thanks to the use of the bladed hoe, strong-rooting grass weeds can be successfully uprooted even in heavier soils. Other problem weeds, such as cow vetch, hemp-nettle, windgrass, or burdock, can also be controlled with the bladed hoe. • Sow the winter cereal in October, in rows with spacing of at least 20 cm. • When the cereal is at the 3-leaf-stage, control sprouting weeds with 1-2 harrowing procedures. • After using the harrow and as the winter cereals begin tillering, root out the yet intact, well-rooted grass weed between the rows with help of a duckfoot-bladed hoeing device. The duckfoot bladed hoe may also be used in combination with the harrow. |

| The finger weeder is the only mechanical hoe that also controls weeds within the row thanks to a slanted position and adjustable overlap of the finger plates, and it greatly reduces manual labour. It offers good performance for most row crops. • Pass once with the harrow 2 to 3 days after sowing the soy (blind harrowing), when many seed weeds have al-ready sprouted. At this moment, the harrow is able to efficiently cover or expose the weeds (up to 90 % efficiency), but avoid damaging the soy seedlings. • A second round with the harrow, applying little tine pressure (a precision tined-weeder recommended), is possible when the soy plants have developed their first pair of leaves. • From the soy's two-internode stage (plant height of about 15 cm) onwards,... |

| The false seedbed technique reduces the weed seed bank in the topsoil and, as a result, significantly reduces competition of annual weeds in the succeeding crop. • Prepare a regular seedbed 2 to 4 weeks before the planned seeding date of the next crop. • Let the weeds germinate and grow to the 2- to 4-leaf stage, the most effective stage for weed control. • Uproot the weeds to a depth of 3 to 5 cm using a harrow comb or a flexible or chain harrow. • If (a) weed density is high, (b) if you have 7 to 10 days available for sowing the crop, or if (c) weed competition in the following crop is very critical, repeat the procedure a second time before sowing the crop as usual. Notes • Weed seed germination is highest in humid soil with a fine tilth. If... |

| • In spring, with a soil temperature of at least 8 °C, place a pot full of cereal or maize grains into water and allow it soak for 24 hours. • Spread out the soaked grains on about 20 cardboard or plastic plates, pot traps, stockings with adequate mesh size or similar materials. Sealable containers must have several holes; through which the worms can access the trap. • Position the traps at a depth of 10 cm with at least 10 to 15 traps per field. The more traps per ha, the more reliable the results. Cover the traps with earth to soil-level and mark the locations. • After 7 to 10 days, dig out the traps, collect them and count the wireworms. • If one or more wireworms per trap is found, the field is infested quite strongly: economic losses are to be... |

| The stubble cultivation cuts the dock roots below growth points. The vegetative plant parts are then cut off from the water and nutrient supply, and regrowth is inhibited. Practical recommendation • Summer dock treatment is especially worthwhile in dry summers with catch crop cultivation and after early maturing crops (winter barley, whole-crop silage) or with an early tillage of grass-clover. • After grass-clover lay or cereal harvest, undercut the dock plants at a depth of 12-15 cm with a skim plough (without skimmer) with a support wheel, a stubble cleaner or an overlapping flat cultivator. • Bring the roots to the surface by passing over the field with a spring-tine harrow every 7-14 days. Additionally, apply a rotary harrow in heavy soils to... |
