Cows Urine-Dung Extract Foliar Spraying as a Complementary Pest Control Method against Boll-Worm Complex on the Cotton Plant

A field experiment was conducted In the 2017 and 2018 cotton seasons to evaluate a novel approach as a complementary method to the chemical control against Lepidopteran larvae of both Pink bollworms, Pectinophora gossypiella (Saunders) (Fam. Gelechiidae) and Spiny bollworm, Earias insulana (Boisduval) (Fam. Noctuidae). Origin products such as cow`s urine- dung extract and crud neem oil had used in this study. Two different treatments of cow�s urine-dung extract were prepared as manner, (1: 1) and (1: 4) (cow�s urine-dung extract: water) (v: v), other two treatments were prepared with the addition 50 ml of neem oil to each to produce two treatments of (1: 1: 50) and (1: 4: 50) (cow�s urine-dung extract: water: neem oil) (v: v: v). All treatments were applied to cotton plants by foliar spray. The evaluation of the foliar spraying of cow`s urine-dung extract and their combinations with neem oil treatments conducted over two consecutive periods each season from (mid-June) to (late-July), and from (early-Aug. ) to (late-Sept. ). The pooled data for both the seasons clearly showed that bollworm complexes density under all the treatments of the cow`s urine-dung extract and their combined with neem oil were found significantly superior lesser than that of the check, and there are no significant differences between each treatment than others in each season and over the two consecutive periods. Neem oil did not add an advantage to the cow�s urine-dung extract treatments either (1: 1) or (1: 4) (cow�s urine-dung extract: water). The results indicated that the cow`s urine-dung extract treatments were more effective during the period from mid-June to late-July on bollworm complexes vs. the period from early-Aug. to late-Sept. the results refer to the cow`s urine-dung extract has the ability to inhibit the bollworm complexes on cotton plants from the beginning of flowering to the boll maturity at a level that can delay apply the pesticides and reduce their use. The present study clearly revealed that cow`s urine-dung extract can safely and effectively be incorporated in an integrated pest management program against bollworm complex density on the cotton plant.
