Seed can be cleaned using a dry heat treatment to remove the pathogen with some success. [9] A treatment of 85° for 3–5 days is effective for removing the pathogen. Different cucurbit seeds respond to this treatment in different ways, and some species (large-seeded squash, wax gourd, bottle gourd) have reduced germination following a dry ...
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
Colletotrichum orbiculare is a plant pathogen of melons and cucumber. It causes the disease anthracnose that can effect curcubits causing lesions on various parts of the plant. It can effect cucumbers, melon, squash, watermelon and pumpkin, especially when the weather is rainy, humid and warm. It can be transmitted by seed as well as soil and ...
Organic systems on average also have 50% more organisms. This data has some issues because there were several results that showed a negative effect on these things when in an organic farming system.

The U.S. Food and Drug Administration (FDA) published a notice from the Florida-based company Saturday. The company said in the press release that the recalled cucumbers were shipped in bulk ...
The definition of agrifood systems' resilience is adapted from Tendall et al.'s definition of food system resilience, which is “capacity over time of a food system and its units at multiple levels, to provide sufficient, appropriate and accessible food to all, in the face of various and even unforeseen disturbances”.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
'Magic seeds' and drought-resistant chickens The foundation have funded corn crop researchers in Africa for more than a decade, and the report touts the promise of what Bill Gates calls “magic ...
