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 ...
Lethal yellowing (LY) is a phytoplasma disease that attacks many species of palms, including some commercially important species, such as the coconut and date palm. In the Caribbean, it is spread by the planthopper Haplaxius crudus (former name Myndus crudus ) which is native to Florida, parts of the Caribbean, parts of Australia and Central ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
A food safety hazard is any biological, chemical, or physical property that may cause a food to be unsafe for human consumption. Identify critical control points A critical control point (CCP) is a point, step, or procedure in a food manufacturing process at which control can be applied and, as a result, a food safety hazard can be prevented ...

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]
