Triclopyr {[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid}, 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid], and 3,6-dichloropicolinic acid were applied to the foliage of juvenile crop plants at 0.002, 0.009, 0.03, 0.14, and 0.56 kg/ha. Corn (Zea maysL.), oat (Avena sativaL.), wheat (Triticum aestivumL.), grain sorghum [Sorghum bicolor(L.) Moench], and kleingrass (Panicum coloratumL.) were generally more tolerant to the herbicides than were peanuts (Arachis hypogaeaL.), cotton (Gossypium hirsutumL.), cucumber (Cucumis sativusL.), and soybean (Glycine max[L.] Merr.). Triclopyr was usually more phytotoxic to corn, oat, grain sorghum, and kleingrass than either 2,4,5-T or 3,6-dichloropicolinic acid at 0.14 and 0.56 kg/ha, but few differences occurred among herbicides at lower rates. Kleingrass was not affected at any rate of 3,6-dichloropicolinic acid. Wheat tolerated most rates of all three herbicides. At 0.56 kg/ha, triclopyr and 3,6-dichloropicolinic acid caused greater injury to peanuts than did 2,4,5-T; whereas, 2,4,5-T and triclopyr were more damaging to cotton and cucumber than 3,6-dichloropicolinic acid. The three herbicides at 0.14 and 0.56 kg/ha killed soybeans. Soybean injury varied from none to severe at 0.002 to 0.03 kg/ha, depending upon species investigated, but many plants showed morphological symptoms typical of the auxin-type herbicides.

A introdução de cultivares de soja resistentes ao dicamba possivelmente aumentará o uso desse herbicida no manejo de plantas daninhas no Brasil. Parte de todo herbicida aplicado atinge o solo, provocando intoxicação de culturas cultivadas em sucessão e contaminação do solo e da água. Nesse sentido, a seleção de espécies indicadoras para realização de bioensaios se torna uma importante ferramenta para avaliar o comportamento desse herbicida no ambiente. O objetivo do estudo foi identificar plantas sensíveis ao herbicida dicamba, para fim de indicação de resíduo desse herbicida no solo. O estudo foi conduzido em casa de vegetação, utilizando delineamento inteiramente casualizado, em esquema fatorial 6x10, com quatro repetições. Sendo, o primeiro fator composto pelas espécies de plantas (Phaseolus vulgaris, Citrullus lanatus, Cucumis sativus, Beta vulgaris, Glycine max e Solanum lycopersicum), e o segundo fator pelas doses do herbicida dicamba (0; 4,5; 9,0; 18,0; 36,0; 54,0; 72,0; 108,0; 144,0; 216,0 g de e.a ha-1), utilizando como substrato inerte areia lavada. Aos 14 e 21 dias após a emergência foram atribuídas notas de intoxicação as plantas e coletado a parte aérea. Os mais altos valores de intoxicação visual foram observados nas culturas do feijão e soja, já melancia, pepino, beterraba e tomate também se comportaram de forma sensível, no entanto, com valores de C50 mais altos. Os sintomas visuais de intoxicação e a produção de massa seca destacam o feijão como a espécie mais indicada para a avaliação da presença de resíduos do herbicida dicamba.

Iron Reductase

Four papaya (Carica papaya L.) cultivars were cultured aeroponically or in perlite to determine the magnitude, timing, and root locality of Fe reductase induced by Fe deficiency. Five soybean [Glycine max (L.) Merrill] lines with a known range of Fe-deficiency chlorosis scores were cultured in perlite for comparison. Speed of inducement of Fe reductase activity was determined in plants cultured without Fe for 0 to 17 days. Location of Fe reductase activity was determined by sectioning roots from the tip to 60 to 70 mm proximal to the root tip from plants cultured without Fe for 16 to 19 days. The Fe reductase system was induced in all papaya cultivars after 7 to 11 days without Fe, and activity increased through 17 days. Iron reductase activity in all papaya cultivars was comparable to the most tolerant soybean line. The zone of highest activity was the apical 10 mm of roots. These results indicate that papaya roots are highly efficient in induced Fe reductase activity. The highest activity in root tips underscores the importance of maintaining a healthy, continually growing root system with numerous growing points when culturing papaya in alkaline substrates.
