[10][11] Based on their different host species, the plant pathogenic fungi of this species complex are divided into approximately 150 special forms (formae specialis, f.sp.). Currently, no cultivar or hybrid meets all of these criteria. American Journal of Botany: 64- If you have larvae infested soil and do not want to kill the … Recombination events may occur via somatic hybridisation and the parasexual cycle. cubense tropical race 4 (VCG 01213/16) associated with Cavendish bananas in Laos."

Second-generation breeding using those new tetraploids as both parents has tended not to yield good results, because the first generation contains the Gros Michel triploid gene set intact (plus possibly useful features in the added fourth chromosome set), but in the second generation, the Gros Michel gene set has been broken up by meiosis. For you, that means that having a wet potting mix (watering too much) and leaving on the soil organic material (dead leaves, for instance) can trigger the presence of this slime. Rust diseases occur most often in mild, moist conditions. [4] TR4 later spread to Vietnam[5] and Laos,[6] as well as to the Middle East being reported in Pakistan and Lebanon.

The yellow houseplant mushroom (Leucocoprinus birnbaumii) is a yellow to white fungus often seen growing in potting soil used in houseplants. Since these fungi live only on decaying plant matter, they do not harm living plants. It occurs naturally in a moist and warm environment.

Thousands of acres of rain forests and former palm oil plantations were shifted to banana production.
