MENACE OF RAGWORT.
EFFORTS FOR ERADICATION.
FURTHER TESTS WITH MOTH.
[BV XELEGEAPH. —OWN CORRESPONDENT.]
TE AWAiIUTC, Wednesday.
A statement of the progress made at the Cawthroa Institute with the moth introduced in the hope that it will control or eradicate ragwort has been received by Mr. W. J. Broadfoot, M.P. for Waitomo, from Dr.* C. J. Eeakes, Director-General of Agriculture. Dr. Reakes stated that supplies of this moth, Tyria jacobeaea, were imported some time ago, and tests were carried out at the Cawthron Institute with a view to ascertaining whether the insect would attack plants of economic value. These tests showed negative results, bat at about the time it was proposed to commence liberation a report was received from abroad that potatoes had been attacked by the Tyria. The institute, therefore, commenced further tests which have now been practically completed. Starvation tests on potatoes are proving negative, and steps are now being taken to arrange for the distribution of the insects should the final results indicate that liberation may be undertaken without risk. The final results should be known in the course of a few days.
