Crop Watch: Assessing impact of April drought and frosts

Crop Watch: Assessing impact of April drought and frosts >More in © Tim Scrivener The rain has saved crops, although it is too late for some crops where the damage has already been inflicted. For example, winter cereals in the north have lost tillers and look thin. While most crops have benefited, rain has also resulted in the expected flush of weeds which will need dealing with. There is some debate on how the April frosts may have affect oilseed rape yields. West AICC/Southwest Agronomy (Avon) The transformation from cold dry April to cool wet May is ample proof that we live in a maritime northern hemisphere country which has weather rather than a climate. It’s what keeps my job challenging and interesting. 

Crop Watch: Spring weather cuts septoria, sclerotinia risk

Crop Watch: Spring weather cuts septoria, sclerotinia risk >More in Sclerotinia sprays in OSR are being delayed until temperatures improve © Tim Scrivener The current cold, dry conditions have reduced disease pressure, especially for rain splash-spreading diseases like septoria in wheat and sclerotinia in OSR. Crop and grass growth is also being held back with soil temperatures still lower than this time last year. For wheat crops in the south, this equates to being about a week behind last year. AICC/Southwest Agronomy (Avon) Despite the cold dry weather, cereal crops growth stages are about where to be expected for the time of year. 

Vets say paradigm shift in horse deworming attitudes needed

Horsetalk.co.nz The commonest types of worms that infect equids are the small strongyles (also known as cyathostomins). A group of British equine veterinarians says an anthelmintic resistance disaster is looming unless horse owners radically change their ways. In a letter to the journal Veterinary Record, David Rendle and colleagues from the British Equine Veterinary Association (BEVA) anthelmintic working group reported the findings of a small-scale survey into the use of fecal worm egg counts (FWECs) and anthelmintic sales. The seriousness of the problem is highlighted by the fact that resistance to all currently available classes of anthelmintics has been reported in both the cyathostomins (small redworm) and ascarids (large roundworm). Furthermore, there is currently no prospect of new drugs in the pipeline.
