Rains during Tropical Storm Elsa over the past week brought needed water to much of the state, between about 0.5 and 3". This combined with warm weather ahead will move the crop forward to continue to set pegs and fill pods. As canopies continue to grow and close, lower leaves will retain dew and stay moist longer, which can encourage development of disease. This is part of why LLS infection typically starts near the bottom of the canopy. Large rank canopies later in the season (normally around 90 days or so), including from Bailey and Bailey II, can also impede fungicide penetration and coverage into the middle. Adding systemic fungicide action to the tank in these cases can help to increase effective coverage.
Depending on when we planted, which variety, irrigation, etc., fields range from just starting to peg (R2), to pod fill (R6), to having closed the row and received an application of growth regulator. The pictures attached show growth of some varieties across planting dates and fields near Blackville. For the most part peanut are looking good across the state.
Scouting School
On Thursday, July 29 we will be conducting a scouting workshop in Cameron for insects and diseases in cotton, peanut, and soybeans. More information with links to register for the workshop are included in the attached flyer.
