A classification methodology for the risk of weed infestation using fuzzy logic
Weed Research, 2008 Despite modern weed control practices, weeds continue to be a threat to agricultural production. Considering the variability of weeds, a classification methodology for the risk of infestation in agricultural zones using fuzzy logic is proposed.

WEEDS INFESTING WHEAT CROP IN ROHTAK, HARYANA
PARIPEX INDIAN JOURNAL OF RESEARCH, 2022Multiple field visits were performed to investigate weed flora of wheat fields in Rohtak district of Haryana, conducted during 2018 which revealed infestation of 28 weed species comprising 15 families of grasses and broadleaf weeds.The weeds were identified with the help of available literature and through comparison with the already identified weed ...

The Prediction of Weed Infestations: Concepts and Approaches
EPPO Bulletin, 1984The role of studies on the population biology of weed species is examined and the utility of such studies in the design of weed management systems assessed. It is argued that the development of predictive models of the population behaviour of weed species is likely to be crucial to the critical evaluation of weed control programmes in the future ...

Weed Infestation in Turmeric in Okinawa, Japan
Weed Technology, 2008A field experiment was conducted in Okinawa, Japan from 2005 to 2007 to evaluate the effect of purple nutsedge and other weeds on turmeric growth and yield and determine the effective weed-control period to minimize crop interference. Treatments consisted of all weeds removed at 70, 115, and 160 d sequentially after planting (DAP), all weeds except ...

Risk prediction for weed infestation using classification rules
2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009This paper proposes a fuzzy classification system for the risk of infestation by weeds in agricultural zones considering the variability of weeds. The inputs of the system are features of the infestation extracted from estimated maps by kriging for the weed seed production and weed coverage, and from the competitiveness, inferred from narrow and broad ...

Infestation and spatial dependence of weed seedling and mature weed populations in corn
Weed Science, 2002Abstract Knowing the distribution of weed seedlings in farmer-managed fields could help researchers develop reliable distribution maps for site-specific weed management. With a knowledge of the spatial arrangement of a weed population, cost effective sampling programs and management strategies can be designed, so inputs can be selected and applied to ...

Weed mapping technologies in discerning and managing weed infestation levels of farming systems
Research on Crops, 2020The advent of robust sensing technologies in remote and proximal sensing systems has led to the generation of accurate weed maps thus enabling precise weed management (PWM). The data from the weed maps are crucial input for crop-weed discriminating algorithms and also decision support models that quantify the risk posed by the weeds on the fields.

CONTROL OF MIXED WEED INFESTATION IN WINTER WHEAT [PDF]
, 2021 During 2016-2017 and 2017-2018 a field trial with winter wheat variety “Enola” was performed. The experiment was situated on the experimental field of the Agricultural University of Plovdiv, Bulgaria. Herbicide products with mixed mode of action were evaluated - Osprey Extra, Atlantis WG, Abak and Atlantis Flex. The application of Atlantis WG – 0.50 kg
