Abstract

Agricultural-origined polluting is one of the greatest problems of humanity nowadays, as great as producing food for every people in the world. We wanted to prove the relevance of new UAV based technologies in agriculture, and their efficiency in the decreasement possibilities in chemical usage. Our research shows that the European Green Deal could be accessible (or available) with precision farming combined with drone technologies. Introduction Agriculture is one of the most polluting areas of human activity, because of using fertilizers, insecticides, pesticides and herbicides. However, almost 8 billion people have to eat. Humanity has just one possibility to solve the problems of 21th century: with new technologies. If we want to achieve the agricultural chemical decrease goals of the European Green Deal by the year 2030 (50%), we have to develop and use new technologies, for example agricultural drones in pest and noxious weed control. Advantages of drones (UAV) are the following: no treading, no compression and most importantly approximately -30% need of chemical dosage can be achieved (diploma thesis, in press)! Using agricultural drones is legal and widespread in many countries of the world, but in Hungary only the experimental use is accepted yet. Cirsium arvense and other „injurious weeds” are causing problems in certain regions of the world (Europe, Canada, New Zealand etc.). Cirsium arvense is an erect perennial rhizomatous thistle. It is usually 0.5 - 1.0 m tall, distinguished from all other thistles by dense clonal growth, creeping horizontal lateral roots and male and female flowers are on separate plants. Cirsium leaves glabrous below with many marginal spines.[1] The traditional method of chemical weed contol (for perennial weeds like Cirsium arvense, Convulvulus arvensis, Asclepias syriaca…) is a „blanket application” on the field with glyphosate (or other total herbicide) by tractor with 5 l/ha dosage in solution 300 l/ha (with 4 l/ha Nitrosol (Liquid nitrogen (30%) fertilizer) and 0,01% Trend 90), which means the whole parcel plot is being sprayed, no matter if there is any weed or not. Our research is closely related to the trend of the European Union: experimenting necessary doses of the allowed chemicals to the new treatment technologies for drones. In this research we were focusing on Cirsium arvense, a geophyton weed which has an overwinter body in the soil, so defence is very difficult against it. The best way to eliminate geophytons is the treatment with absorbed chemicals, such as glyphosate, in autumn or spring before seeding.
