A problem that may be faced by some growers of agarwood, attacked by armyworm or scientifically known as Atteva Sciodoxa. Armyworm, a leaf-eating caterpillar is considered to be the most destructive pest causing damage by complete defoliation of agar plantations. The intensity of attack can cause death of well-grown trees due to complete defoliation.
