Struktur komunitas hama tiga kultivar cabai rawit pada pengaplikasian pestisida nabati

Abstract

The utilization of plant-based pesticides and the selection of cultivars of cayenne pepper have not been well optimized by farmers. The purpose of the study was to analyze the types of cayenne pepper pests, examine the association of cayenne cultivars against pest attacks, and analyze the application of commercial vegetable pesticides to pest visits. The research method used was experimental with a completely randomized design. The sample of this study consisted of three cayenne cultivars, namely Sret, Mhanu XR, and Green Chakra. The research instrument used observation sheets of pest communities before and after the application of vegetable pesticides. The type and number of pests are directly observed and identified in the laboratory. Data on the influence of cayenne cultivar on pest populations were analyzed by ANOVA test while the effect of using vegetable pesticides using t-test. The results showed that the types of pests found were Aphis sp., Polyphagotarsonemus sp., Thrips sp., Bactrocera sp. and Chrysodeixis sp. Statistical tests showed cayenne cultivar did not significantly influence pest visits while the application of plant-based pesticides had a significant effect on the decrease in Thrips sp. and Aphis sp. The conclusion of this study, namely five types of pests attack three cayenne cultivars, the selection of three chili cultivars does not affect pest visits while the application of vegetable pesticides can reduce the number of pest visits Thrips sp. and Aphis sp significantly.

Produksi Tanaman Cabai Rawit Pada Pola Lanskap Agroforestri Tanaman Karet

“…Kondisi tersebut menyebabkan pertumbuhan dan produksi tanaman cabai rawit pada pola lanskap agroforestri lebih baik dari pada pada penanaman monokultur (Gambar 4 dan Gambar 5). Faktor lain adalah serangan penyakit pada sistem penanaman monokultur yang lebih tinggi dibandingkan pada sistem penanaman agroforestri dengan tanaman karet, terutama penyakit layu Fusarium sebanyak 27,78% dan penyakit kerdil sebesar 12,50%, yang dapat menyebabkan penurunan produksi tanaman mencapai 60% (Semangun, 2000;Kurniahu et al, 2020).…”

Daya Adaptasi Pertumbuhan Tanaman Cabai Rawit Pada Sistem Agroforestri Tanaman Karet

“…Pengamatan pertambahan tinggi dan jumlah daun tanaman cabai rawit umur 42 HSPT pada kedua sistem penanaman, menunjukkan sedikit peningkatan dengan pertambahan tinggi tanaman setinggi 16,03 cm dan jumlah daun 36 helai pada sistem agroforestri tanaman karet yang sama dengan pertambahan tinggi tanaman dan jumlah daun tanaman cabai rawit pada sistem penanaman monokultur berturut-turut 15,37 cm dan 36 helai. Hal ini disebabkan serangan patogen penyebab penyakit tanaman yang tinggi, sehingga pertumbuhan dan perkembangan tanaman cabai rawit terhambat (Kurniahu et al, 2020).…”
