This is to try to prevent the growth of long weak sprouts that are easily damaged at planting and thus provide an entry point for disease. Seed should be assessed for disease by examining washed samples. Some diseases such as silver scurf and black scurf are significant problems in pre-pack potatoes and can be reduced by applying appropriate fungicide seed dressings. Although it may be past the time for applying many liquid treatments, dust formulations could still be used at planting. Growers must refer to the manufacturers label recommendations before applying seed dressings, as incorrect application of some products may affect crop emergence.
Cultivations Wait until ground conditions are suitable before cultivating.
Compaction caused by forcing a seed bed in poor conditions restricts root growth, leaving the crop susceptible to nutrient deficiencies, drought and lower yields. Aim to produce a fine tilth that retains moisture and assists the performance of residual herbicides. Monitoring soil temperature For rapid emergence and growth, potatoes should be planted into warm soil, with temperatures consistently 8oC or greater. This is very important for some varieties such as Pentland Dell, which are sensitive to cold temperatures and may display the disorder little potato , in which tubers are initiated before foliage has emerged. If soil temperatures are low, it is especially important that the seed is held in cool conditions prior to planting.
