| • 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... |

| 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. |

| • 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... |
