Facial Eczema Risk Rating: MEDIUM - HIGH
Spore count results are not following the expected trend this season with northern sites recording higher counts than those in the south. Historically sites in the Linton/Tokomaru to Okuku South have risen first. This could be because there is not enough moisture in the southern area to make the spores bloom.
Cheltenham took out the top count last Thursday with a 232,000 average. Other sites of concern were Kelvin Grove - 85,000, Kairanga South - 70,000, Halcombe - 45,000 and Ohakea - 35,000. Colyton lifted from 10,000 to 25,000 and we also did see a slight increase of 5,000 in Okuku South from the previous week to 20,000.
Non-sentinel farms at Cameron's Line, Rongotea, Rangiwahia and Makino Road all came in over 25,000.
