Seedcare in brassicas

Brassicas

In the cultivation of brassicas, seed and soil-borne fungi can cause germination and emergence problems. Immediately after sowing, fungi on or in the vicinity of the seeds come to life. For brassicas, these major fungi are treated with Apron XL and Maxim 480FS. Both FarMore® Technology seed-treatment products ensure that the germinating seed develops into a strong plant: the basis for a good brassica yield.

Brassica diseases

ALTERNARIA SPP. – leaf spots | The diseases Alternaria brassicae, Alternaria brassicicola and Alternaria raphani are common in brassicas. Leaf spots cause a loss of seedlings. Dark brown to black lesions develop on the leaves, usually with a yellow edge. As these lesions grow, the whole leaf may discolour. The disease develops most rapidly at a temperature of

FUSARIUM SPP. fusarium wilt | The disease Fusarium oxysporum is common in brassicas. Characteristic of fusarium wilt are wilting and total root rot. A pinkish mildew may also be visible. The disease may be seed, wind or soil-borne or spread on plant material. At a temperature of 27°C and a pH of less than

LEPTOSPHAERIA SPP.black leg | The disease black leg is common in brassicas. Black leg causes leaf spots varying in colour from greenish brown to tawny, yellow or nearly white. Spots contain numerous, dark carpophores. The spots tend to be circular or oval in shape and between 0.5 and

PYTHIUM SPP. root rot | The disease root rot is common in brassicas. Root rot is a secondary parasite which particularly affects young plants. The disease is first visible at the roots, which turn blackish brown and show signs of rotting. Thick-walled resting spores develop in the diseased tissue which

RHIZOCTONIA SPP.black scurf | The disease black scurf is common in brassicas. High humidity will intensify black scurf. The disease can be identified at an early stage by leaf spots just above the ground and in the middle of the outer leaves. These lesions can prevent or impede further crop growth. At high humidity levels

Table of diseases | efficacy of FarMore® Technology

FarMore® Technology can improve seedling emergence and vitality by effectively controlling a range of seed and soil-borne fungi. The table shows the control spectrum of Maxim 480FS (Fludioxonil) and Apron XL (Metalaxyl-M). It indicates which fungi that pose a risk to brassicas the FarMore® solutions can control.
