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 ...
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]
The disease starts out as yellowing and drooping on one side of the plant. Leaf wilting, plant stunting, browning of the vascular system, leaf death and lack of fruit production also occur. [8] F. oxysporum f. sp. melonis attacks muskmelon and cantaloupe. It causes damping-off in seedlings and causes chlorosis, stunting and wilting in old plants.
In the early stages, MLND causes long yellow stripes on leaves. Unlike maize streak virus disease though, the streaks of MLND are wider. As the disease advances, the maize leaves become yellow and dry out from the outside edges towards the midrib. MLND can also cause dwarfing and premature aging of the plants.
Cadang-cadang is a disease caused by Coconut cadang-cadang viroid (CCCVd, Cocadviroid cadangi), a lethal viroid of several palms including coconut (Cocos nucifera), African oil palm (Elaeis guineensis), anahaw (Saribus rotundifolius), and buri (Corypha utan).
7. Soy Can Affect Fertility in Men. Soy has come a long way. Once dismissed as “hippie food,” today it’s a popular protein alternative for vegetarians and vegans.
Papaya Lethal Yellowing Virus (PLYV) is an isometric viral plant pathogen, tentatively assigned to the genus Sobemovirus, [1] that causes lethal yellowing disease of the papaya plant. [ 2 ] The virus infects only Carica papaya , Jacaratia heterophylla , J. spinosa , Vasconcellea cauliflora , V. monoica and V. quercifolia , all from the papaya ...
