HASTINGS FACIAL ECZEMA SPORE COUNT MONITOR - Week ending 12 March 2020
The average count across the region increased 12,500 last week to just over 40000 this week. The hotspots at the top of Dartmoor Road increased to from 50,000 to 95000, and 20,000 to 195,000 and Eskdale.
As expected spore counts have risen quickly after the rain last week. Now is a good time to start doing your own pasture cuts. You need a paper bag full - 60grams (¾ of a bread bag), cut as close to the ground as possible without contaminating the sample with dirt. It takes a while when grass is short, but if that’s what the stock are eating then take the time to sample correctly.
In most areas the risk is still classed as low, as counts go over 30,000 and pasture covers are low conditions become more dangerous for stock. Counts over 60,000 are considered high and even short term expose can cause disease.

The cooler nights will be helping keep the lid on the spore counts. Looks like more rain in the coming week, heavy rain can wash spores into the soil and decrease spore count on a temporary basis, and the cooler nights
