| The non-tilled, constantly covered soil has improved water retention and also shows a better carrying capacity during harvest, and is less affected by weed infestation, compaction, nutrient-leaching, and erosion. Stockless farms especially benefit from the nitrogen input of the legume-green manure. • At the beginning of August, carry out 1 to 2 stubble-tillage operations after cereal or rape harvest. • Sow the wintering forage peas in October. • At the end of May, kink the peas' stems with a knife-cylinder roller, after which you drill in the maize with row cleaners. The green manure lying on the ground must be properly dried off for sowing. • The mineralisation performance, lowered due to the soil cover, can be compensated for with focused nitrogen... |

| 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... |

| • 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. |

| 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,... |

| • 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... |
