[ 2 ] The virus infects only Carica papaya , Jacaratia heterophylla , J. spinosa , Vasconcellea cauliflora , V. monoica and V. quercifolia , all from the papaya ...
However, the use of herbicides can cause phytotoxic effects on non-targeted plants through wind-blown spray drift or from the use of herbicide-contaminated material (such as straw or manure) being applied to the soil. [5] Herbicides can also cause phytotoxicity in crops if applied incorrectly, in the wrong stage of crop growth, or in excess. [1]
Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...

Banana Xanthomonas Wilt (BXW), or banana bacterial wilt (BBW) or enset wilt is a bacterial disease caused by Xanthomonas vasicola pv. musacearum. [1] After being originally identified on a close relative of banana, Ensete ventricosum, in Ethiopia in the 1960s, [2] BXW emanated in Uganda in 2001 affecting all types of banana cultivars.
But both of these activities put women at risk of developing health problems, including respiratory issues. Here’s what researchers want you to know about household hazards facing women — and ...
Citrus greening is distinguished by the common symptoms of yellowing of the veins and adjacent tissues (hence the "yellow dragon" name given by observing Chaozhou farmers as early as the 1870s [1]); followed by splotchy mottling of the entire leaf, premature defoliation, dieback of twigs, decay of feeder rootlets and lateral roots, and decline in vigor, ultimately followed by the death of the ...
