“…Recommended practices such as fumigation and stale seedbed/frequent tillage, however, were not available for use in this study because it would have interfered with the concurrent soil-monitoring experiment (Ghimire et al, 2018). Control with herbicides is difficult because most currently available herbicides do not kill the dormant tubers (Peerzada, 2017), and nutsedge control is only marginal (Bangarwa et al, 2009). Similarly, Adcock et al (2008) found that preemergence herbicides did not reduce nutsedge penetration of PE mulch.…”

“…The bare ground plots were hand weeded, which has been shown to be an effective, although very expensive, method to control nutsedge (Bangarwa et al, 2010). Morales-Payan et al (1997) and Peerzada (2017) report that mechanical and cultural control of nutsedge through cultivation and other means usually is not economical or realistic, and an intensive, integrated approach is vital. There are reports that a stale seedbed method and/or repeated hand weeding or hoeing are effective in reducing nutsedge pressure (Wang et al, 2009).…”

Plasticulture systems with polyethylene (PE) mulch and drip tape are common for production of peppers (Capsicum annuum L.) in the United States because of their soil warming, moisture conservation, and other advantageous effects. However, disadvantages include disposal costs and plastic pollution of the environment and temperature stress in warm climates with black mulch. Use of biodegradable plastic mulches (BDMs) is becoming more common, as they provide the same benefits of PE mulch without the disposal problems. In 2017 and 2018, we conducted experiments in Knoxville, TN, comparing production of pepper fruit with five different BDM [one white-on-black (WOB) and four black], one black PE mulch, one brown creped, paper mulch, and bare ground control treatments. We also measured the durability and effectiveness of weed suppression of the different mulches over the growing season compared with a hand-weeded bare ground control. Most mulches were degraded, with 40% to 60% of the soil exposed by the end of the season, with the exception of the paper mulch, which was completely degraded at the end of both seasons. Yields were similar among treatments in 2017, with the exception of Naturecycle, which had the lowest yield. Weed pressure was severe, especially in 2018, largely due to early penetration of all mulches except paper by nutsedge. Due to the early and season-long weed pressure and heat stress in black mulches, there were fewer healthy plants in all black-colored mulch treatments in 2018, leading to reduced yields in these treatments. Paper mulch was the only treatment that prevented nutsedge growth; therefore, this treatment and the hand-weeded bare ground treatment had the greatest yields in 2018. WOB also had yields comparable with paper and bare ground plots in 2018, likely due to the cooling effect of the white mulch. The results suggest that in hot climates and in fields infested with nutsedge, paper mulches perform best for midseason pepper cultivation due to the cooling effects and superior weed control.

Interference of weeds in vegetable crop cultivation, in the changing climate of Southern Europe with emphasis on drought and elevated temperatures: a review

et al. 2018

It is challenging to predict the changes in weed flora that may occur because of changes in global climate. Limited data are available on the effect of climate change and drought conditions on weed flora and their competitiveness in Southern Europe. Future predictions by scientists indicate reduced and untimely rainfall, along with increased temperatures in this region. Weeds possess a variety of developmental and physiological mechanisms, including senescing, increased leaf cuticular wax deposition, well-developed palisade parenchyma in the leaves, high root/shoot ratio, stomatal closure, peroxidase accumulation and symbiosis with endophytes that enable them to adapt to drought and high temperatures. Because of high adaptability of weeds to adverse environmental conditions, it can be assumed that under future warmer and drier environmental conditions, their growth will be favoured, while the competitiveness of vegetable crops against weeds will be decreased. It is important to highlight that the predicted decrease in overall rainfall levels throughout the year may lead to increased problems of herbicide residues (carryover effects) to following crops. The current paper provides an up-to-date overview of the adaptation mechanisms of weed species commonly found in Southern Europe, in order to expand the available knowledge regarding their response to drought and elevated temperatures. Emphasis is placed on revealing the effects of drought and increased temperatures on vegetable–weed competition and, most importantly, its effect on vegetable crop yield.

“…A espécie Cyperus rotundus L. representa 60 a 80% da população de plantas daninhas na cultura da cana-de-açúcar, causando de 20 a 30% de perdas na produção, quando seu controle é atrasado em oito semanas (Peerzada, 2017). Por possuir reprodução quase que exclusivamente via rizomas, tubérculos e bulbos basais (Rahnavard et al, 2010) seu controle com herbicidas e capinas é dificultado, principalmente porque os tubérculos podem ter diferentes níveis de dormência .…”

“…No Brasil, alguns herbicidas são registrados para uso em pré ou pós-emergência (inicial, tardia ou jato dirigido) da cana-de-açúcar e de C. rotundus como o sulfentrazone, diclosulam, imazapic, imazapyr, halosulfuron, ethoxysulfuron, MSMA, 2,4-D, trifloxysulfuron e glyphosate (Rodrigues;Rodrigues;. Entretanto, a eficácia do manejo químico vai depender da dose do herbicida, do número de aplicações, do banco de tubérculos presente no solo e das práticas de cultivo (Peerzada, 2017).…”
