SKRIPSI PENGARUH SAAT PEMBERIAN DAN BERBAGAI JENIS FUNGISIDA SISTEMIK PADA INTENSITAS PENYAKIT TROTOL (Alternaria porri (Ell) cif ) PADA TANAMAN BAWANG PUTIH (Allium sativum .) DATARAN RENDAH
ABSTRACT
A research to study the influence of time of applica- tion and kind of sistemic fungicide on Alternaria porri (Ell) Cif disease and yield of low land onion plant (Allium sativum L.) held on March 1996 until May 1996 in Girirejo, sub district Tegalrejo, Magelang Regency at the Latosol soil with pH 6, 5, 320 meters above the sealevel.
The research is factorial trial (4x3) with randomized complete block, consists of three replications. Fist fac- tor is time of application 0, 5, 7, 9 days. Second factor is kind of fungicide: Topsin M 70 WP, Delsene MX-200, Bay leton 250 EC.
The result of the trials shows:
1. Different time of application can, increase the weight of fresh onion plant after harvest, the weight of dry onion plant after harvest, the weight of fresh onion, the weight of dry onion.
2. The Topsin M 70 WP, Delsene MX-200, Bayleton 250 EC of fungicide able to prevent the intens ity of desease attack and the rate of infection.
3. The using the Topsin M 70 WP with application once in five days indicates the most effective result to prevent the intensity of disease attack and give the higher pro- ducts.
4. Each fungicide gives similar response to increasing frequency of application.
