“…Although solarization may be used to control weeds in areas with hot climates (Abu-Irmailleh 1991;Al Masoom et al 1993) or in areas that have periods of prolonged light intensity during the summer (Standifer et al 1984), this weed control technique typically is not effective in more temperate regions. Nevertheless, soil heating of very small areas (e.g., 1 m 2 ) by solaria may be effective as a predictive tool when used to compliment traditional scouting and management techniques.…”

At locations in Argentina and the United States, solaria (miniature, portable, plastic greenhouses or a plastic sheet approximately 1 m2) were placed on field soils in autumn or late winter in an attempt to predict summer annual weed densities. Initial emergence of summer annual weeds covered by solaria commenced weeks before that of weeds in exposed seedbeds. Cumulative emergence of many species in solaria reached asymptotes before crops were sown. At asymptotic cumulative emergence, densities of dominant weeds in solaria (common lambsquarters, green foxtail, and large crabgrass) were correlated with weed densities occurring 4 wk after sowing, the typical time for making postemergence weed control decisions. These results indicate that solaria may supplement seedbank-sampling techniques for predicting weed densities in crops.

“…A solarização tem sido utilizada com sucesso no controle de plantas daninhas parasitas (Abu-Irmaileh, 1992;Braum et al, 1988;Jacobsohn et al, 1980) e da maioria das plantas daninhas anuais, cuja reprodução se realiza por sementes (Al-Masoom et al, 1993;Cardoso, 1989;Egley, 1993;Horowitz et al, 1983;Rubin & Benjamin, 1984;Standifer et aL, 1984). Quanto às plantas daninhas que se reproduzem vegetativamente, como é o caso da tiririca, essa mesma eficiência não tem se repetido (Braun et aL, 1988;Cardoso, 1989 ;Egley, 1993 ;Rubin & Benj amin , 1983 ;Rubin & Benjamin, 1984), sendo requeridas, portanto, maiores informações sobre o desenvolvimento dessas espécies sob condições de solarização.…”

RESUMOUm ensaio foi conduzido em condições de campo, durante o verão, com o objetivo de avaliar o potencial da técnica de solarização do solo no controle da tiririca (Cyperus rotundus L.). O delineamento experimental utilizado foi o de blocos casualizados com três repetições, e os tratamentos num esquema fatorial 2 X 2 X 3, sendo duas situações de cobertura (com e sem plástico transparente de 300 µm de espessura), dois estádios de desenvolvimento da planta daninha (vegetativo e florescimento) e três períodos de cobertura com plástico (15, 30 e 60 dias). A temperatura do solo sob solarização teve um aumento médio de 4,3°C em relação à testemunha, atingindo valores superiores a 50°C em determi nados horários. Observou-se, também, um acúmulo da ordem de 400 % nos teores de CO 2 na atmosfera do solo solarizado. Nessas condições houve inibição da brotação dos tubérculos e diminuição no peso de matéria seca de todas as partes estudadas da planta. Houve redução na taxa de multiplicação dos tubérculos, reduzindo-a de 1:11 para 1:4, quando coberta no estádio vegetativo e para 1:9 quando a cobertura se realizou no estádio de florescimento. Houve, ainda, diminuição na ordem de 20% na viabilidade dos tubérculos remanescentes.Palavras-chave: Plantas daninhas, controle físico, temperatura, biologia, estratégia reprodutiva. ABSTRACT Th e ef fe ct s of so il so la ri za ti on wi th tr an sp ar en t pl as ti c on pu rp le nutsedge (Cyperus rotundus)The research was conducted under field conditions during the summer period, to evaluate the solarization effect on purple nutsedge (Cyperus rotundus) control. The experimental design was randomized blocks with three replications. The treatments were arranged in a factorial scheme 2 X 2 X 3, with two cover conditions (with and without transparent plastic sheet, 300 µm thickness), two periods of covering (vegetative and flower stages), and three cover periods (15, 30 and 60 days). The soil temperature under solarization was 4.3°C higher than the control, reaching more than 50°C at certain times of day. An increase of 400% was observed in the CO2 concentration in the atmosphere of solarized soil. Under these conditions the tuber sprouting was inhibited and the dry weight of all parts of the plant was decreased. The rate of tuber multiplication was decreased from 1:11 to 1:4 when the plant was covered at the vegetative stage, and to 1:9 when it was covered at the repr oductive stage. A decrease of 20% in tuber viability was also observed.

“…Reduced weed pressure on lettuce following SS has been documented since the 1990's (Al-Masoom et al 1993;Campiglia et al 2000). More recently it was reported to extend throughout two or more consecutive crops and further prolonged in the absence of soil disturbances after the treatment (Candido et al 2008;Hasing et al 2004;Patricio et al 2006).…”

“…Soil solarization was repeatedly documented for successful weed suppression, as well as for increased yield response, in both field and greenhouse lettuce (Al-Masoom et al 1993;Campiglia et al 2000;Hasing et al 2004;Patricio et al 2006). However, few comparative studies are available of the effect of different solarizing materials on weed suppression and lettuce yield, and a comparison of different lettuce cultivars was limited to the strip-solarization technique (Hasing et al 2004).…”

Effect of different solarizing materials on weed suppression and lettuce response

The effect of four solarizing plastic materials on weed suppression and yield response of two lettuce cultivars ('Bacio' and 'Moringa') grown during two consecutive seasons was investigated at Metaponto (40°2 3′N; 16°47′E; 10 ma.s.l.), southern Italy. All solarization treatments suppressed winter and summer weeds with no significant difference among the plastic materials, although biodegradable film was less efficient in controlling common purslane and common amaranth. Weed infestation at the harvest of both lettuce cultivars was not affected by the solarizing material, whereas fewer weeds were found in the plots grown with 'Bacio' than with 'Moringa'. Lettuce yield in two successive growing seasons was always significantly higher in solarized plots than in nontreated control, without any statistical difference among the plastic materials. Yield and head quality of cv. 'Bacio' were higher than 'Moringa' in the first growing season, but the opposite occurred in the second crop. Soil solarization was confirmed to be effective for weed management in field lettuce crops in the Mediterranean areas, although weed suppression may be affected also by the lettuce cultivar.Choice of solarizing materials, when similarly effective on weeds and crop yield, should take into account also their cost. Low density polyethylene plastics emerged as the best choice in conventional lettuce crops as highly effective as, and less expensive than the other materials, whereas the use of biodegradable films should be limited to organic lettuce systems.
