A pathogen transmitted by the eriophyid mite, Aceria tulipae, infects a number of Gramineae producing symptoms similar to wheat spot mosaic virus (1). An electron microscope study of leaf ultrastructure from systemically infected Zea mays, Hordeum vulgare, and Triticum aestivum showed the presence of ovoid, double membrane bodies (0.1 - 0.2 microns) in the cytoplasm of parenchyma, phloem and epidermis cells (Fig. 1 ).

O consumo alimentar de larvas de 3º estádio de Phytalus sanctipauli Blanch. foi estudado em laboratório. Os insetos foram criados individualmente e alimentados com aveia (Avena sativa), milho (Zea mays) ou trigo (Triticum aestivum) ou com as três espécies juntas. A quantidade (massa seca) ingerida de raiz e semente, respectivamente, foi maior em trigo (28,5 mg), menor em aveia (16,4 mg) e intermediária no milho (22,6 mg). O consumo de folha foi semelhante em aveia (18,2 mg) e trigo (19,8 mg) e significativamente superior ao de milho (2,1 mg). Avaliando-se a plântula como um todo, o consumo de trigo foi superior tanto quando as espécies vegetais foram oferecidas isoladamente (89,8 mg) quanto em conjunto (56,9 mg). O peso fresco médio das larvas ao término da alimentação foi maior em trigo (100,2 mg) e milho (102,2 mg) do que em aveia (85,9 mg). O número médio de plantas destruído por larva foi marcadamente maior em trigo e aveia (27,4 e 24,9, respectivamente) comparado com milho (0,9).

Em um Latossolo Roxo de Santo Ângelo (RS), e em um Podzólico Vermelho-Escuro de Eldorado do Sul (RS), ambos com textura argilosa, submetidos o primeiro à exploração com cultivo convencional de trigo (Triticum aestivum L.) e soja (Glycine max L.) e sob setária (Setaria anceps L.), e o segundo à exploração com capim-pangola (Digitaria decumbens L.), siratro (Macroptilium atropurpureum L.), plantio direto com aveia (Avena bizantina L.)/milho (Zea mays L.) e área sem vegetação, foi realizado o presente trabalho durante a safra de verão (1990/1991), com o objetivo de avaliar a estabilidade e a agregação do solo sob diferentes sistemas de cultivo. Constatou-se, nessa avaliação, que as gramíneas perenes por meio do seu sistema radicular tiveram grande efeito na agregação e estabilidade dos agregados do solo e que os teores de carbono orgânico, de ferro e alumínio-oxalato, argila e grau de dispersão tiveram também efeitos na agregação do solo, porém insuficientes para explicar as variações entre o diâmetro médio ponderado dos agregados sob os diferentes sistemas de cultivo.

Glyphosate [N-(phosphonomethyl)glycine] applied at 1.1 kg/ha to wheat [Triticum aestivum(L.) ‘Arthur 71′] plants increased height and fresh weight of soybean [Glycine max(L.) Merr. ‘Ransom′] seedlings planted in the pot at time of application of the glyphosate as the number of wheat plants treated increased from 5 to 30/pot. Height and fresh weight of the soybean seedlings also increased as the rate of glyphosate applied to wheat plants (5/pot) increased from 1.1 to 6.7 kg/ha. Increasing the rate of glyphosate from 1.1 to 6.7 kg/ha, however, reduced the height and fresh weight of soybeans when 30 wheat plants/pot were treated. In addition, when 6.7 kg/ha of glyphosate were applied to wheat plants, soybean-seedling plant height and fresh weight decreased as the density of wheat plants per pot increased from 5 to 30. The14C-glyphosate exuded into the soil from treated wheat plants was characterized by thin-layer chromatography. Trace amounts of the radio-label were present on thin-layer plates of leaf and stem extracts of corn (Zea maysL.) plants, which were growing in the same pots with the treated wheat plants. The zone of activity had the same Rf value as the glyphosate standard.

Field and greenhouse experiments were established to determine the phytotoxicity of Canada thistle [Cirsium arvense(L.) Scop.] residue on crop growth. Field examination of infestations showed that as Canada thistle shoots increased in an area, the number of kochia [Kochia scoparia(L.) Schrad.], marshelder (Iva xanthifoliaNutt.) and foxtail barley (Hordeum jubatumL.) plants decreased. Conversely, as Canada thistle shoots decreased, the aforementioned annual and perennial plants increased. In greenhouse studies, roots and shoots of Canada thistle that were mixed with soil reduced the growth of sugarbeet (Beta vulgarisL. ‘Mono Hy D2’), wheat (Triticum aestivumL. ‘Centurk’), alfalfa (Medicago sativaL. ‘Dawson’), and Canada thistle seedlings. Corn (Zea maysL. ‘Jacques No. 1004’) and dry edible beans (Phaseolus vulgarisL. ‘Great Northern No. 59’) grown in soil treated with Canada thistle residue were affected to a lesser extent. When Canada thistle residue was mixed with soil, crop growth was inversely proportional to the amount of Canada thistle residue added to the soil. Both roots and shoots of Canada thistle were toxic to crops when mixed with the soil. The effects of Canada thistle residue on crop growth lasted for about 60 days. Neither autoclaving residue and soil nor fertilization of soil had any effect on residue toxicity. Canada thistle leaf leachate inhibited the growth of sugarbeets watered daily with the leachate.
