Fall armyworm damage pdf

"With severe fall armyworm larvae damage (50% of the total crop) on standing maize, the plots were demarcated diagonally, and the plants along the diagonal line had a small amount (0.10-0.15 g Fall Armyworm (FAW) Spodoptera frugiperda (J. E. Smith) - the status, challenges and experiences among the SAARC Member States (virtual), 27-28 January, 2021. sprays as an emergency response to minimize the spread and damage to crops. But this could lead to increased cost of production to growers. It cannot be ruled presence of certain organisms causing damage and potentially yield reduction. For Fall Armyworm, the procedure is quite simple: Determine the field to be sampled. For a smallholder, this is typically less than 2 ha. If the fields were planted at different times, with different varieties, or with Symptoms and signs ♦ Young caterpillars (1-3 instar stage) feed on leaves and cause window pane-like damage, initially appearing to only "scratch" the leaf. ♦ As caterpillars grow, they feed on large amounts of leaf tissue causing large ragged and elongated holes on leaves, leading to a shredded appearance. ♦ The caterpillars can also feed on tassels and ears. The Fall Armyworm (FAW) is the most destructive pest of many economically important crops across the globe. FAW is native to the tropical and subtropical region To control FAW larvae at 5% damage to reduce hatchability of freshly laid eggs, spray 5% NSKE OR Azadirachtin 1500 ppm @ 5ml/ litre of The key to managing fall armyworms is to detect infestations before they have caused economic damage. Fall armyworm larvae feed primarily during the night and during cloudy weather. During the day, look for armyworms under loose soil and fallen leaves on the ground. The presence of chewed leaves can indicate armyworms are present. Small larvae • Fall Armyworm (FAW) in Africa has the potential to cause maize yield losses in a range from 8.3 to 20.6m tonnes per annum, in the absence of any control methods, in just 12 of Africa's maize-producing countries. This represents a range of 21%-53% of the annual production of maize averaged over a three year period in these countries. • Cultural control to suppress Fall armyworm damage before infestation occurs. • Control measures for Fall armyworm once infestation occurs e.g mechanical, biological and chemical control, habitat management and use of botanicals. Cultural control is the practice of modifying the crop environment to make it less friendly for Fall armyworm Habits and Damage . Fall Armyworm. Fall armyworm damage often appears as a browned or burned-out patch resembling drought damage (Figure 8). The damaged patch will usually increase in size as the fall armyworm con ­ sumes more foliage. The brown color results from drying of the plant due to dehydration after army­ worms chew tender growth. Fall Armyworm ACT Fall Armyworm (Spodoptera frugiperda) is a new pest in Africa, attacking maize, but can also feed on other crops. The caterpillars are mainly found feeding on young maize plants, but they can also attack a range of other crops including millet, sorghum, rice, wheat, sugar cane and vegetables. Leaf damage is usually The fall armyworm's head has a predominant white, inverted Y-shaped suture between the eyes. Moths are typically attracted to fields of late-maturing corn to lay their eggs. The larvae are primarily daytime feeders. They appear in corn fields late in the season, from mid-July through harvest. Fall armyworm, unl
