Aphids an autumn threat to cereals and winter oilseed rape

A long and warm autumn allows field work to continue. Unfortunately, the current conditions are the perfect time for aphids to develop and attack emerging winter cereals. After the sugar beet and grain maize harvests are complete, aphids are also moving into the new winter oilseed rape sowings. The young seedlings are ideal food for them, leading to a weakening of the plant before winter dormancy. Damage to leaf blades or the transmission of dangerous diseases that cause, in particular, yellow dwarfing of barley leaves, are the greatest bane of farmers.

Cabbage aphid – combating

From mid-September, this species frequently attacks winter oilseed rape, causing numerous yellow, red or purple discolourations to appear on the edges of the leaf blades. Infected plant parts cause stunted growth.

Several preparations can be used to control the cabbage leaf aphid in winter oilseed rape at this time of year; the recommended timing for treatment is the appearance of the first colonies or damage on young plants.

A field trip can thus be combined with an additional feeding cycle using MiRzepak, a compound fertiliser with micronutrients, which is combined with insecticides. The additional application of NanoMi will provide protection against fungal diseases of possibly weakened leaves.

nanoMI – quick plant rescue

nanoMi is the only liquid foliar fertiliser in Poland with a very high amount of nano-colloidal silver of 10,000 ppm per kg of fertiliser. Composed of 100% natural ingredients, this fertiliser improves the condition of plants, while nano-silver shows strong antibacterial, antifungal and antiprotozoal properties. Preparations based on nanoparticles show activity even at low quantities, which can be a great alternative to conventional plant protection and stimulation measures.
