Embodiment Construction

[0041] One of the main advantages of the fertilizer guest of the present invention compared to other calcium fertilizers known in the prior art is the high persistence in the crop under all weather conditions and during the entire agricultural cycle. Therefore, one of its main benefits is that it acts as a continuous calcium pump. This avoids the need to apply calcium in multiple foliar applications as is required when using calcium liquid fertilizers such as calcium chloride.

[0042] This beneficial effect of the novel fertilizer is due to the surface chemical composition of the fertilizer, which in addition to Ca 2+ or CO 3 2- In addition to other ionic species (such as CaOH + , CO 3 h - or CO 3 CaOH - (confirmed by XPS or TOF-SIMS measurements)). They are all activated under wet conditions (rain, dew) and allow for increased calcium bioavailability. In particular, it has surprisingly been found that the effective amount of calcium provided by the fertilizer guest...

Abstract

The present invention refers to a permanent solid calcium fertilizer suitable against fruit physiological disorders and pests, characterized in that it comprises more than 98.5% weight of calcium carbonate. It is also an object of the invention the use of this fertilizer for the protection of agricultural crops against pests and preferably for the protection of pear and / or apple crops.

Description

[0001] describe technical field [0002] The present invention relates to the field of chemistry, and in particular the present invention relates to novel calcium fertilizers suitable for use against fruit physiological disorders and pests. Background technique [0003] Over the past few decades, chemical insecticides have played an important role in plant protection and pest control. However, these chemical pesticides are known to have risks and effects associated with their use in human health and the environment. In order to reduce these risks, a common legal framework (Directive 2009 / 128 / EC) was established for the sustainable use of pesticides. This directive minimizes or prohibits the use of chemical pesticides in certain areas. [0004] Directive 2009 / 128 / EC encourages the development of alternative methods or technologies to reduce dependence on the use of pesticides. Therefore, there is a need to develop new types of natural products suitable for controlling agri...
