please suggest management and control measures for Post flowering stalk rot (PFSR) in Rabi Maize (Nov to March). this is very serious Disease of Maize specially for Rabi season crop. It appears after Silking and Tassling stage where crop instantly dries in patches or whole field with in 2 to 3 days.
Kindly see here too..

Post flowering stalk rot in Rabi Maize ??. Available from: https://www.researchgate.net/post/Post_flowering_stalk_rot_in_Rabi_Maize [accessed Apr 3, 2017].
Post flowering maize stalk rot is favored by drought stress which predisposes plants to fungal stalk pathogens this is particularly the issue with charcoal rot. Since drought stress is involved particulary related to post flowering a timely irrigation at tasseling and grain fill might be very useful to mitigate the issues. In relation to drought stress hybrids which are with the stay green genetics and other mechanisms which promote drought tolerance will be important. In addition the use of moderated plant populations with balanced nutrition where potassium application is at a moderate rate along with the nitrogen application. The rotation of maize with a previous crop of a legume like soybean would be useful. Seed application of starter phosphate can be helpful for increasing agressive root systems. Control of fungal foliar and insect pests can predispose the stalk rot. Weeds are also a predisposing factor. The use of soil testing will be important for optimizing the plant nutrition which is a factor reducing damage for stalk rot. Besides the use of balanced potassium with nitrogen the identification of Si deficiency can be remedied leading to greater pathogen, pest and stalk stiffness. Select hybrids for their adaptation and pest resistance. The use of eary maturity hybrids can avoid exposure to some of predisposing drought issue. Hope some of these suggestions are useful for your quest.
