Brazilian agrochemical company Cropchem has introduced a new multisite contact fungicide, Kasan Max 750 WG, which has mancozeb as active ingredient and is especially aimed at combating Asian soybean rust - the worst disease faced by this crop in Brazil.
With water dispersible granules formulation (WG), Kasan Max 750 WG does not dust in the preparation of the syrup and favors the efficacy of systemic products, which can be applied together. The multisite fungicide acts at various points in the fungus metabolism, preventing the disease from manifesting. This molecule potentiates the action of specific site fungicides, which must be associated in the management for a complete control.
According to the manufacturer, Asian soybean rust "has become increasingly resistant in the last few seasons and the specific action fungicides can no longer contain single infestations of this disease. This is one of the main concerns of producers today." The active ingredient mancozeb, from the chemical group dithiocarbamates, has been considered, in Brazil, one of the main solutions in resistance management.
In addition to Asian rust, Cropchem's fungicide also controls the following diseases: Cercospora kikuchii, Corynespora cassiicola and Septoria glycines. In addition to soybeans, Kasan Max 750 WG is also indicated for other crop diseases.
In cotton, the product fights against Ramularia areola, while in rice it controls Pyricularia grisea. The product could control dreaded Mycosphaerella fijiensis in banana, and is efficient against Alternaria solani and Phytophthora infestans in potato.
Kasan Max 750 WG can also be used for the control of Colletotrichum lindemuthianum in beans, Phaeosphaeria maydis in maize, Phyllocoptruta oleivora and Phyllosticta citricarpa in citrus, Venturia inaequalis in apple, as well as Plasmopara viticola in grape.
