NEWS A dry spring so far? Not really... A sk Gauteng smallholders whether they think this spring has been particularly dry and most will answer “yes”, plaintively asking as a followup “when are the rains coming?” Well, here's the bad news: comparing our rainfall figures from the beginning of September each year to the 20th of October (just as we went to press) for each year since 2000, this year's precipitation of 34mm places 2016 more than halfway up the rankings. Both last year (13mm) and 2014 (21mm) were drier when comparing the days of September and October up to the 20th. 2005 was the driest for these days, at only 8mm, while three years later, in 2008 we were blessed with a very early rainy season, at 205mm, the wettest period we have recorded.

According to a veterinary source this is not unusual at this time of year, with cases of the disease having been confirmed in Marister and in Ekurhuleni’s south eastern townships. Newcastle disease is a highly contagious viral disease with a 90% mortality among poultry, and with some effect also among waterfowl, pigeons and ostriches. The virus is easily transmitted by infected birds, can survive outside of the host bird for a while, can spread by airborne transmission, and can also be spread by visitors bringing it to one’s plot on their footwear, vehicles etc. The disease is also notifiable, meaning that cases must be reported to the State Veterinarian in one's area, who will likely order the culling of an infected flock and may, depending on the severity of the outbreak, declare a quarantine over an area.
