Appearing Within . By alternating strobilurin materials with other effective materials, and by limiting the number of strobilurin applications per season, the chance for development of resistance to the materials will be reduced. Information in the guidelines will be included on all new labels. Even though there will be a transition time before all labels have the new wording, all growers will benefit from following the new guidelines now. Guidelines pertaining to vegetables and potatoes are summarized below.
Similar guidelines are available for other crops listed on strobilurin labels.
For all other diseases, no more than three sequential applications before alternation to an unrelated fungicide that is effective in controlling the causal fungus. Therefore, if Flint is used for two applications on cucurbits, only two additional sprays can be made, regardless of whether they be Quadris or Flint. Likewise, if Quadris is used for two applications on cucurbits, on two additional sprays can be made, regardless of whether they are Flint or Quadris. It is probably impossible to identify a food from a domesticated source that has not been genetically modified by humans prior to molecular biotechnology. Genetic improvement started with selection of organisms with superior traits, followed by breeding for additional genetic improvement.
