One of the most important moments in the protection of orchards is the protection against rodents, which are often able to cause great damage in the period of rising temperatures before the end of winter, therefore, sometime in February and March. In our region, fruit growers most often seek protection from rodents such as the vole and the field mouse, and it is often the case that mice and rabbits are a problem, especially because it is characteristic of them that love young plantations of apples, pears and cherries.
Due to the difficult conditions during the winter, these species, due to the need to feed, inflict damage that will to influence to the plant, often so to dry or weaken the fruit. Successfully solving this problem depends on the dedication of the fruit grower and the way he takes care of his orchard, not only in the winter but also in the rest of the year.
Rodents need to be stopped not to make a shelter. All the branches that remained posle rezidbe take out of the orchard. Keep in mind that these animals can also find shelter in a pile of cut grass, because of that posle kosidbe you need to clean the orchard.
Hazard assessment based on the amount of active holes
In regular tours orchards, not only in winter, but also in spring and autumn, determine the danger of rodents. Pay attention to the traces of mouse activity – whether you notice the appearance of hallways on the surface, feces, or damage to trees. You can get a safer check if you bury all the holes you notice in the orchard with earth, and check them the next day, whether and which number is reopened.
Check in the spring is suitable sometime in late February and early March. Check it out how many holes do you notice per 100 m². Roughly these measures show whether you are under a bigger or smaller problem with mice – if you have two holes on this surface it is a weak attack, up to five holes is a measure for a mediocre problem, anything over five means you have serious problems with mice.
In the fall these measures vary – Less than 10 holes is a small danger, anything between 10 and 20 is a medium danger, and more than 20 holes is a sign that you are under a big mouse attack.
Damage can be prevented by using ready-made baits
The measure to prevent damage, which is recommended by the Forecasting and Reporting Service for Plant Protection, is to place registered ready-made baits in the holes, after which backfilling is mandatory. Also, it is recommended to place protective nets around the trunk, in order to reduce or even completely prevent the damage caused by wildlife.
