The Use of Optical Systems Greenseeker RT 200 with Differentiated Distribution of Herbicides
In the practice of agriculture, the one-stage technologies of differentiated distribution of pesticides in real time, ensuring the optimal agrotechnical timing of activities for plant protection, has a predominant use because of the two-stage technological processes are long in time and labor-intensive. The efficiency of the use of the optical system GreenSeeker RT200 to assess the contamination of winter triticale crops by changing the NDVI index (Normalized Difference Vegetative Index) with differentiated distribution of herbicides in real time has shown. Currently intensive work on the creation of sensors to account for small-scale inhomogeneity of the distribution of weeds within fields on crops of tilled cultures and in narrow grain crops and leguminous crops are performed. (Research purpose) The research purpose is to evaluate the efficiency of the use of the optical system Green Seeker RT 200 to account for the weeds spread in the field. (Materials and methods) We performed the accounting of weed infestation on the conventional eye-numerical method by continuous survey of crops and counting of weed plants on the accounting sites (50x50 cm), located at the same distances on the diagonal of 13 selected areas, as well as using the optical system Green Seeker RT 200, working with its own radiation source and measuring NDVI(Normalized Difference Vegetation Index). (Results and discussion) We have estimated the infield heterogeneity of the distribution of weed vegetation activities on crops of winter triticale in LLC «KlinAgro» of the Moscow region on the area of 22 hectares with the use of optical sensor Green Seeker RT200. We have developed a map-job to perform the technological operation of differentiated distribution of herbicides. (Conclusion) The high efficiency of the use of the optical system Green Seeker RT-200 to account for the spread of weeds on crops has been confirmed. It was shown that the differentiated distribution of herbicides, taking into account the intra-field heterogeneous weed infestation with the use of Green Seeker RT-200 system, will reduce the consumption of Dialin Super by 23 percent compared to the continuous distribution of the average dose of the drug, and reduce the cost of agricultural products, reduce the pesticide load on the environment.
