This research aim to know influence of organic pesticide application (kinds of concentration and materials to control caterpillar of grayak (Spodoptera Exiqua HUBN.) at shallot crop (Asclonicum Allium L). This research is executed in Garden Attempt Of Faculty Of Agriculture University Muhammadiyah of Malang. This Research use Random Device of Group consisting of 2 factor by 3 restating times and use analysis Contrast of Orthogonal. Factor of I: Kinds Of Extract Pesticide Organic (B) which consist of 3 level : (B1) Extract of Gadung ; ( B2) Extract of Pahitan ; ( B3) Ekstrak Tobacco. Factor of II: Concentration Extract which consist of 4 level : (Concentration K1) 1 ml / lt water; (Concentration K2) 2 ml / lt water; (Concentration K3) 3 ml / lt water; (Concentration K4) 4 ml / lt water. Research result show there no real interaction between treatment combination kinds of organic pesticide extract (B) and concentration (K) to all perceptions parameters. For application kinds of organic pesticide materials to result and growth not have an effect on except to reality of parameter is percentage of pest attacks and fresh weight of corm, extract of paitan (B2) show highest value. For the concentration of extract (Concentration K) 4 ml/lt assign value best for the parameter of perceptions of[is percentage of pest attack, long of crop, heavy run dry corm, but at parameter perceptions of leaves amount, wide of leaf, fresh heavy totalize crop, heavy run dry crop, fresh heavy of corm, corm diameter and corms amount giving of concentration 3ml/lt assign value the bestness. Usage kinds of organic pesticide extract of and gadung of paitan give good result in controling pest attack caterpillar of grayak (Spodoptera Exiqua HUBN.) however not differ reality with control (Curacron 500 EC). Organic Pesticide of extract of gadung at concentration 4 ml/lt can be used to control caterpillar attack of Spodoptera exigua HUBN. Need the existence of further research concerning influence of usage of organic pesticide in controling pest attack at dry season.
