THE EFFECT OF THE APPLICATION OF TURMERIC, GINGER AND BETEL LEAF RHIZOM EXTRACT PESTICIDES ON THE PERCENTAGE OF LEAF CATERPILLAR PEST ATTACKS (Helicoverpa armigera Hbn ) ON PEANUT PLANTS (Arachis hypogaea L)

Abstract

The purpose of study This is For knowing the influence application pesticide vegetable extract rhizome turmeric , ginger and leaves betel to percentage attack pest caterpillar leaves ( Helicoverpa armigera Hbn .) on plants peanut soil ( Arachis hypogaea L ). Study This is test arranged field​ based on Randomized Block Design (RBD). First factor is pesticide plant (P). Pesticides vegetable consists of of 3 namely without pesticide / control (P0), pesticide extract rhizome turmeric (P1), pesticide extract ginger (P2) and pesticides  extract leaf betel (P3). The second factor is dose spray (D) consists of of 3 treatments namely : without spray (D0), dose spray 200 cc/plot (D1), dose spray 250 cc/plot (D2), dose spray 300 cc/plot (D3). So that obtained 10 combinations treatment , repeated as many as 3 times. Data analysis using analysis analysis of variance ( ANOVA ) and analysis testing different between treatment tested with different test Duncan's real at the level 5% confidence .

Research result show that giving pesticide vegetable ( extract) rhizome turmeric , ginger and leaves betel ) and dosage spray influential real to to percentage attack pest caterpillar leaves (Helicoverpa armigera Hbn .) at the age of 4 and 12 MSS. There is real interaction​ between Giving pesticide vegetable ( extract) rhizome turmeric , ginger and leaves betel ) and dosage spray on all observation parameters . Combination dose spray 300 cc/plot, pesticide extract leaf betel give results percentage attack least pests . This is seen from the average measurement each measurement parameter indicators percentage attack pest caterpillar leaves (Helicoverpa armigera Hbn .)
