The sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae) (SCA), has become a major pest of grain sorghum since its appearance in the USA. Several grain sorghum parental lines are moderately resistant to the SCA. However, the molecular and genetic mechanisms underlying this resistance are poorly understood, which has constrained breeding for improved resistance. RNA-Seq was used to conduct transcriptomics analysis on a moderately resistant genotype (TAM428) and a susceptible genotype (Tx2737) to elucidate the molecular mechanisms underlying resistance. Differential expression analysis revealed differences in transcriptomic profile between the two genotypes at multiple time points after infestation by SCA. Six gene …

Oil palm production in Indonesia illustrates the intense pressure that exists worldwide to convert natural ecosystems to agricultural production. Oil palm production has increased because of expansion of cultivated area rather than due to average-yield increases. We used a data-rich modelling approach to investigate how intensification on existing plantations could help Indonesia meet palm oil demand while preserving fragile ecosystems. We found that average current yield represents 62% and 53% of the attainable yield in large and smallholder plantations, respectively. Narrowing yield gaps via improved agronomic management, together with a limited expansion that excludes fragile ecosystems, would save 2.6 million …

Genetic Variability In Fusarium Oxysporum F. Sp. Vasinfectum Causing Damping-Off Of Cotton (Gossypium Barbadense L.) Seedlings [Research Note], Reda Helmy Sammour, Salah Abdel Moemen, Eman Elagamy Jun 2021

Genetic Variability In Fusarium Oxysporum F. Sp. Vasinfectum Causing Damping-Off Of Cotton (Gossypium Barbadense L.) Seedlings [Research Note], Reda Helmy Sammour, Salah Abdel Moemen, Eman Elagamy

The Philippine Agricultural Scientist

The genetic variability of Fusarium oxysporum f. sp. vasinfectum isolates from Gossypium barbadense L. seedlings were assessed using pathogenicity, mycelial compatibility, and RAPD analyses. The results showed that the disease incidence percentages and compatibility percentages considerably varied, extending from 33.2 to 86.6 % and 6 to 60 %, respectively in North Egypt and from 33.3 to 66.6 % and 0.0 to 20% in South Egypt. It also showed that the isolates ISO-8 and ISO-19 had the lowest disease incidence (33.2%) as compared with isolate ISO-5 (86.6%). Results of the mycelial compatibility had a reversible relationship with disease incidence percentage. Cluster …

The purpose of this study was to assess the potential for biocomposite films to biodegrade in diverse climatic environments. Biocomposite films based on polyethylene and 30 wt.% of two lignocellulosic fillers (wood flour or flax straw) of different size fractions were prepared and studied. The developed composite films were characterized by satisfactory mechanical properties that allows the use of these materials for various applications. The biodegradability was evaluated in soil across three environments: laboratory conditions, an open field in Russia, and an open field in Costa Rica. All the samples lost weight and tensile strength during biodegradation tests, which was …


Physical–Chemical Properties, Droplet Size, And Efficacy Of Dicamba Plus Glyphosate Tank Mixture Influenced By Adjuvants, Estefania Gomiero Polli, Guilherme Sousa Alves, Joao Victor De Oliveira, Greg Robert Kruger Jun 2021

Physical–Chemical Properties, Droplet Size, And Efficacy Of Dicamba Plus Glyphosate Tank Mixture Influenced By Adjuvants, Estefania Gomiero Polli, Guilherme Sousa Alves, Joao Victor De Oliveira, Greg Robert Kruger

Department of Agronomy and Horticulture: Faculty Publications

Dicamba plus glyphosate tank mixture have been largely adopted for postemergence weed control after the development of dicamba-tolerant crops. Ammonium sulfate is commonly used as water conditioner (WC) to increase glyphosate efficacy, but its use is restricted for dicamba herbicides. The use of non-AMS water conditioner and other adjuvants could be a way to optimize efficacy of this tank mixture while mitigating herbicide off-target movement. The objective of this study was to determine the physical–chemical properties and droplet size distribution of dicamba and glyphosate solutions with and without non-AMS WC alone and tank mixed with other adjuvants and evaluate the …
