| 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... |

| 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... |
