Reduce the risk of mycotoxins in maize silage this season
“It’s not been a typical season for maize, with many crops going into the ground late. Quality and yield is looking variable, therefore it’s important farmers explore avenues which could help maximise quality and minimise dry matter losses between the field and feed-out, this will allow them to reduce purchased feed costs,” explains Lientjie Colahan, technical sales ...

How to store feed pellet
During the rainy season, the air humidity is relatively high. If the feed is not stored properly, it is easy to become moldy and deteriorate. Various nutrients in the moldy feed are destroyed, the nutritional quality of the feed decreases, and even its utilization value is completely lost. After livestock and poultry eat moldy and rotten feed, toxins will accumulate in the animal's body, causing ...

Are endophyte-mediated effects on herbivores conditional on soil nutrients?
Neotyphodium endophytes are assumed to have mutualistic relationship with their grass hosts, mainly resulting from mycotoxin production increasing plant resistance to herbivores by the fungus that subsists on the plant. To study importance of often ignored environmental effects on these associations, we performed a greenhouse experiment to examine the significance of endophyte infection and ...

Influence of root exudates of watermelon on fusarium oxysporum f. Sp. Niveum
Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] production in the same field without rotation of crops leads to disease buildup and poor yields. The purpose of this research was to evaluate the influences of root exudates produced by watermelon cultivars susceptible or resistant to the pathogen Fusarium oxysporum f. sp. niveum (FON). At low concentrations of root exudates ...
