  • genera
  • As part of a move towards a more natural classification of fungi, R.T. Moore proposed in 1987 that Rhizoctonia should be restricted to the type species and its relatives, with unrelated species moved to other genera. (wikipedia.org)
  • germinate
  • Since the fungus that causes gray mold depends on water to germinate on the plant surface, increasing air circulation through fans and reducing the relative humidity by venting or heating (depending on outside temperatures) will help prevent condensation of water on plant surfaces and thereby reduce the occurrence of gray mold. (msu.edu)
  • crops
  • Experiments have demonstrated that 44% of twigs were infected with brown rot when crops were left untreated compared to only 4% when the crop was treated. (wikipedia.org)
  • corn
  • In the areas of Illinois where corn has been planted and is growing, many of the seedlings appear yellow, stressed, and stunted. (illinois.edu)
  • plants
  • Roots are killed back, causing plants to be stunted and spindly. (wikipedia.org)
  • To ensure that samples get to the lab in the best condition, it is better to keep them moist and aerated.Plants are to be dug out with a lump of soil still attached to the roots. (blogspot.com)
  • If root rot occurs, remove and destroy the diseased plants. (msu.edu)
  • Important Info : All parts of plants can cause stomach upset if ingested. (backyardgardener.com)
  • crop
  • Crop root growth can be increased by the presence of earthworm burrows. (missouri.edu)

  • pesticides
  • However, the environmental pollution caused by excessive use and misuse of agrochemicals, as well as fear-mongering by some opponents of pesticides, has led to considerable changes in people's attitudes towards the use of pesticides in agriculture. (apsnet.org)
  • Favorable factors include poor seed quality (such as cracked seed and infected seed), soil temperatures at planting below 50 to 55 deg F, wet soil conditions, soil compaction, slow emergence and growth, fertilizer burn, improper use of pesticides, injury from herbicides, soil crusting, high temperatures ( Penicillium seedling blight--not a problem yet this year!
