Bait Stations for Controlling Voles in Apple Orchards
Bait stations made with polyvinylchloride (PVC) pipe were compared with hand-broadcast applications of rodenticides for achieving long-term control of pine and meadow vole populations (Microtus pinetorum and M. pennsylvanicus, respectively) in two apple orchards in the mid-Hudson Valley of New York. The stations were constructed of three pieces of 1.5-in diameter PVC tubing joined together in t...
متن کاملEconomics and Control of Damage Caused by Low-density Populations of Meadow Voles in Ontario Apple Orchards
Live trapping and questionnaires were used to evaluate amount, distribution, and costs of control of damage to Ontario apple trees by meadow voles (Microtus enns lvanicus) in 1981-82. In a sample of 180 orchards, 5802 (0. trees were damaged or killed by voles. Orchards with high levels of damage (> 2.5%) were smaller than the average orchard in our sample. Application of rodenticides showed no ...
متن کاملEffects of Sulfur Application on Soil pH and Uptake of Phosphorus, Iron and Zinc in Apple Trees
The main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil pH. Two sulfur fertilizers (sulfur alone and sulfur + organic material + Thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil pH and availability of P, Fe and Zn in apple trees dur...
متن کاملLong Term Vole Control in Ontario Apple Orchards
'!he results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Cbnsiderable interest has been ...
متن کاملManagement of Pine Voles
The pine vole (Microtus pinetorum) damages apple trees in western North Carolina, sometimes spectacularly. The current research monitors populations in orchards for several years to compare damage in different management practices. Recommendations for orchard management to reduce damage are devised and used to i l l u s t r a t e the process of a p p l i c a t i o n of basic knowledge. Populati...
