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. |

Die Spatenprobe liefert wertvolle Informationen zum Zustand landwirtschaftlicher Böden. Trotzdem wird sie in der Praxis wenig angewendet. Die BodenDok Mobile-App will dies nun ändern. Die App des Forschungsinstituts für biologischen Landbau FiBL,eine Co-Produktion mit der Fachhochschule Nordwestschweiz FHNW, unterstützt die Landwirte bei der Spatenprobe und weitergehenden Beobachtungen am Boden. Die App führt die Nutzer Schritt für Schritt durch den Beurteilungsprozess und liefert unter anderem Hinweise zur Bearbeitbarkeit des Bodens. Die App ist modular konzipiert, so dass vertiefende und innovative Untersuchungsmethoden zu einem späteren Zeitpunkt ergänzt werden können. |

• 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... |

Multiple cultivations lead to a repeated physical damage of the thistle. Each time it regrows, it uses further nutrients until it is weakened and a new crop will out-compete it. This method is also effective against other root-spreading weeds such as couch grass and bindweeds. • After harvesting grains, perform stubble cultivation with a skim plough or a completely flat-cutting wing share cultivator at a depth of 7-10 cm. • After the thistle plants have re-emerged (maximum 10 cm), repeat the cultivation 1-2 times while increasing the working depth. • Sow a dense, fast-growing catch crop such as vetch or fodder radish after the stubble cultivation to further weaken the thistles. This method only works on dry soils and in dry weather; in wet... |

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... |

Check the state of infestation • When the potato plants start to emerge, walk the field every 7 days in a straight line and check plants at regular intervals. • If clusters of eggs are found on more than every third plant, apply Novodor four days after discovering the first clusters. Apply the agent • Dissolve 5 l of Novodor in 500 l of water per hectare of potatoes. • Novodor can be applied together with copper products. Optimal conditions: • The potato beetles are still in an early larval stage (L1 to L2). • Temperature between 15 °C and 25 °C. • Avoid direct sunlight: spray late in the evening or when the sky is overcast. • No rain is due within 8 hours after spraying. Comments • After a successful treatment, the larvae will turn black after... |
