Univ of Idaho research studies herbicide damage to potatoes caused by heavy rainfall

Farmers throughout southern and eastern Idaho were befuddled by the bizarre symptoms of crop damage that surfaced in their potato fields following a brief period of heavy rainfall in May of 2017. Pam Hutchinson, University of Idaho Extension potato cropping systems weed specialist, has studied the problem – heavy rains prior to potato emergence can move herbicides too deep into the soil, where they’re more accessible by shoots and tuber roots than usual, which could, in turn, cause crop damage.

Dry conditions not hindering potato development in Britain, but common scab might be an issue

Potato planting in Britain has got off to a good start this season, with the dry conditions in some areas not expected to affect emergence. Velcourt Advisory Services agronomist Patrick Levinge says soils have been left very dry by the lack of rain, but at this stage, it should not be having a negative impact on crop development. Common scab is likely to be an issue on susceptible varieties.

Soft rot in potatoes: Ten planting practices to reduce seed piece decay

“The soft rot bacterium that causes seed piece decay is very common, and it has an extensive host range. It survives in soil and surface waters. Soft rot in potatoes is caused by Pectobacterium carotovorum subsp. carotovorum,” says Dr Eugenia Banks, potato specialist with the Ontario Potato Board in Canada.

UK food production to shrink as input inflation hits 24%

Double-digit cost inflation is hitting every single enterprise of British agriculture, casting doubt on the sector’s ability to maintain food supplies in the year ahead. Latest figures from the AF buying group shows that no farming enterprise has been able to avoid the impact of soaring costs, with cereals and oilseed producers seeing the greatest increases at 28%, followed by potatoes, dairy, and beef and lamb producers – all hit by inflation of more than 20%.

Rabobank report: ‘The Russia-Ukraine war’s impact on global fertilizer markets’

Rabobank’s RaboResearch – Food & Agribusiness team released this research report recently. They say that higher fertilizer prices and/or a shortage of fertilizer supply resulting from the war in Ukraine will not have an immediate impact on food prices and/or food production. The first crop-growing regions to be ‘at risk’ are India and Latin America. India is partially out of danger, but Latin America is highly exposed.

Opinion: ‘The future for potatoes: Opportunities and threats’

“Growing potatoes can sometimes feel like it’s a constant battle. From seed import and export restrictions following the UK’s departure from the European Union to a shrinking armoury of crop protection products and pandemic-induced changes in consumer demand. Despite these challenges, potatoes can still be a financially rewarding crop.” This, according to a recent article posted online by Bayer Crop Science in the UK.

Biostimulant Bridgeway proven to combat heat stress in potatoes

Independent field trials have shown for a 4th year that Interagro’s amino acid + peptide biostimulant Bridgeway helps to combat the effects of heat stress in potato crops, enabling photosynthesis and tuberisation to be maintained. Importantly for growers it helped secure yield with significant increases and margin gains over untreated crops.

Crop specialists: This ‘cool pest prediction tool’ comes in handy for potato growers

A weather-based decision support system that originated 15 years ago in the tree fruit orchards of Washington state has branched into the region’s potato fields. The Pacific Northwest Potato Decision Aid System (DAS) collects regional weather inputs and combines that with research-based data on local pest populations. It then alerts growers to when different insect populations may be active.

Researchers developed organic technology from banana plant waste to combat PCN in East Africa

Potato production in East Africa is under increasing threat from the invasive and highly destructive potato cyst nematode (PCN) Globodera rostochiensis. Researchers have now developed an organic technology from banana plant waste material which might well being a practical solution for potato farmers. Dubbed ‘wrap-and-plant,’ the solution involves enclosing potato seed before planting in a thick absorbent paper made from the fibers of banana plants.
