In Brazil, countless insect species attack and damage sugarcane (Saccharum officinarum L.), which is an extremely important crop since it planted on more than 10 million hectares. Among these insects, the billbug, Sphenophorus levis (Coleoptera: Curculionidae), of great importance as larvae open tunnels in rhizome plant, causing high losses. This attracted mainly to vinasse, liquid fraction gen...

telenomus beneficiens is a common egg parasitoid of sugarcane top borer scirpophaga excerptalis; however, in winter time the incidence of the parasitoid on top borer eggs is extremely low. t. beneficiens adults were released at various time durations into sugarcane plots to evaluate the parasitic potentiality of the parasitoid against sugarcane top-borer. the egg parasitoid t. beneficiens of su...

The objective of this work was to study the effect of sewage sludge compost on ammonia and nitrate accumulation in the olive-grove soil. This study has been conducted since 1998. To evaluate sewage sludge compost on soil-grove four treatments were set up in a clay loam soil in Seseña (Toledo, Spain). Every experiment was replicated four times. The applied treatments were sewage sludge compost (...

In last decades, oil spill pollution has become an important issue of concern due to its serious environmental impacts; therefore, necessary actions should be taken to prevent or reduce these types of pollution and their environmental consequences. Natural organic sorbents are emerging as proper choices for oil spill cleanup due to their availability, eco-friendliness, and low cost. In this stu...

Successful transplant production begins with selecting good growing media. Healthy vigorous transplants will be less susceptible to insects, diseases and transplant shock, leading to improved overall crop performance. Formulating organic potting mixes is especially challenging. Organic sources of nitrogen, such as compost, can be inconsistent. Compost chemical, biological and physical character...

Compost is used mainly as an organic fertilizer, but it is also used as bedding material for cattle. Dairy cattle have been identified as a main reservoir of pathogenic Escherichia coli O157:H7. Further, E. coli is regarded as an environmental pathogen that causes bovine clinical mastitis. Hence, its growth in compost spread or compost bedding should be avoided. Physical and chemical conditions...

The objective of this study was to evaluate the agronomic characteristics of sugarcane as a function of the no-tillage system (NTS) compared to the conventional one (CS) with, and without, manuring. The experimental design was completely randomized, using four repetitions, in a factorial scheme 4 x 2. The treatments were: sugarcane NTS on sunnhemp (Crotalaria juncea); sugarcane NTS on jack bean...

Compost stability and maturity are important parameters of compost quality. To date, nearly all compost characterization has been performed using samples freshly collected because sample storage can affect compost stability and maturity evaluation. However, sample preservation is sometimes necessary, especially for scientific research purposes. There is little information available on the effec...

Cotesia flavipes (Cameron) is a parasitoid responsible for maintaining populations of sugarcane borer, Diatraea saccharalis (F.), below economic levels in south Texas sugarcane Þelds. Transgenic sugarcane expressing the snowdrop lectin (Galanthus nivalis agglutinin, GNA) was developed against the Mexican rice borer, Eoreuma loftini (Dyar), the primary pest of south Texas sugarcane. The potentia...
