“…In the present study, we evaluated the effectiveness of using a single DCNN to detect multiple weed species growing in perennial ryegrass. Simultaneous detection of multiple weed species is of paramount importance for precision herbicide application because weeds often grow in mixed stands and various postemergence herbicides, such as 2,4-D, carfentrazone, dicamba, and MCPP, are sprayed to provide broad-spectrum control of various broadleaf weeds (McElroy and Martins, 2013; Reed et al, 2013). For training purposes, E. maculata, G. hederacea , and T. officinale constituted a single category of objects to be discriminated from perennial ryegrass ( Figure 2 ).…”

“…These weed species are commonly found in various cool-season turfgrasses. Herbicides, such as 2,4-D, dicamba, MCPP, triclopyr, and sulfentrazone are broadcast-applied in cool-season turfgrasses for POST control of various broadleaf weeds (McElroy and Martins, 2013; Reed et al, 2013; Johnston et al, 2016; Yu and McCullough, 2016a; Yu and McCullough, 2016b). Precision herbicide application using machine-vision based sprayers will substantially reduce herbicide input and weed control costs.…”

Precision herbicide application can substantially reduce herbicide input and weed control cost in turfgrass management systems. Intelligent spot-spraying system predominantly relies on machine vision-based detectors for autonomous weed control. In this work, several deep convolutional neural networks (DCNN) were constructed for detection of dandelion (Taraxacum officinale Web.), ground ivy (Glechoma hederacea L.), and spotted spurge (Euphorbia maculata L.) growing in perennial ryegrass. When the networks were trained using a dataset containing a total of 15,486 negative (images contained perennial ryegrass with no target weeds) and 17,600 positive images (images contained target weeds), VGGNet achieved high F1 scores (≥0.9278), with high recall values (≥0.9952) for detection of E. maculata, G. hederacea, and T. officinale growing in perennial ryegrass. The F1 scores of AlexNet ranged from 0.8437 to 0.9418 and were generally lower than VGGNet at detecting E. maculata, G. hederacea, and T. officinale. GoogleNet is not an effective DCNN at detecting these weed species mainly due to the low precision values. DetectNet is an effective DCNN and achieved high F1 scores (≥0.9843) in the testing datasets for detection of T. officinale growing in perennial ryegrass. Moreover, VGGNet had the highest Matthews correlation coefficient (MCC) values, while GoogleNet had the lowest MCC values. Overall, the approach of training DCNN, particularly VGGNet and DetectNet, presents a clear path toward developing a machine vision-based decision system in smart sprayers for precision weed control in perennial ryegrass.

Because of the observed effect of aminocyclopyrachlor on reducing seed production in these graminoids, a study was conducted to evaluate the potential effect of aminocyclopyrachlor on the important exotic annual grass downy brome.…”

Aminocyclopyrachlor (DPX-MAT28) belongs to a new class of chemistry known as the Pyrimidine Carboxylic Acids. It is a new generation of herbicides belonging to the family of herbicides known as synthetic auxins. This new generation of chemistry has unique properties at both the molecular and whole plant level that translates into more potent herbicidal activity resulting in increased speed of action and in controlling a much wider spectrum of broadleaf weeds.MAT28 provides an effective, broad spectrum of activity on difficult-to-control species such as ALS-and glyphosateresistant weeds, invasive weeds and brush species. Proposed uses for MAT28 include general weed and brush control on private, public and military lands, including uncultivated agricultural and nonagricultural areas, industrial sites and natural areas. Other proposed uses for MAT28 include the release or restoration of native perennial grasses and use in established industrial and professional turf.

“…However, when these herbicides were applied sequentially, the defoliation rate was 95%. Other information in the literature about the efficacy of aminocyclopyrachlor + metsulfuronmethyl in the control of weed plants was reported by Reed et al (2013), West et al (2011), Ferrel et al (2012 and Kyser and DiTomaso (2013). These authors found that this product was effective in the control of Diodia virginiana, Lantana camara, Cayratia japonica and Linaria dalmatica.…”

-The species Tecoma stans, introduced to Brazil to be cultivated in urban centers as street trees, in parks and gardens, became important pasture weed. The mechanical control of this species is difficult because the plant presents a large number of sprouts when are mowed. Furthermore, the herbicides usually used in pasture have been shown to be inefficient to control it. This research evaluated the trumpet flower control effectiveness using a new herbicide (aminocyclopyrachlor) applied alone in increasing doses to the cut stump for the control of resprouts and mixed with metsulfuron-methyl in applications to intact plant leaves. The experiment with foliar applications used increasing doses of herbicides (aminocyclopyrachlor + metsulfuron-methyl). Applications of only aminocyclopyrachlor to the cut stump and foliar application of a herbicidal mixture (aminocyclopyrachlor + metsulfuronmethyl) were effective in the control of trumpet flower.Keywords: exotic species, trumpet flower, susceptibility to herbicides. RESUMO -A espécie Tecoma stans introduzida no Brasil para ser cultivada nos centros urbanos em arborização de ruas, praças e jardins tornou-se importante planta daninha em pastagens. O controle mecânico dessa espécie é difícil, por apresentar grande número de rebrotas quando as
