Perceptions And Management Of Ventenata By Producers In The Inland Pacific Northwest, Lisa Jones, John Wallace, Kathleen Painter, Pamela Pavek, Timothy S. Prather
Journal of Extension
Ventenata is an annual grass that has invaded agricultural and wildland settings in the Inland Pacific Northwest, causing economic and ecological losses. We know little about producers’ perceived risks and management of ventenata. We present results of surveys in 2011 and 2014 targeting producers across affected counties in Idaho and Washington. Awareness of ventenata and costs to producers increased across that time interval. Respondents attending ventenata Extension events adopted recommended management strategies more than those who did not attend. Our study documents the importance of continued integrated pest management research in concert with stakeholder engagement and education.

Jurnal Kultivasi
Keberadaan gulma pada pembibitan kelapa sawit dapat menurunkan kualitas bibit. Pengendalian gulma di pembibitan awal harus dilakukan secara dengan tangan (hand weeding), karena bibit dapat mati akibat aplikasi herbisida. Aplikasi bioherbisida saliara (Lantana camara) pada bibit kelapa sawit (Elaeis guineensis Jacq.) dapat menjadi alternatif pengendalian gulma yang ramah lingkungan dan mengurangi tenaga kerja. Penelitian ini dilaksanakan di Kebun Percobaan 1 Politeknik CWE, pada November 2019 sampai Februari 2020. Percobaan disusun dalam Rancangan Acak Kelompok, dengan perlakuan: kontrol (tanpa aplikasi bioherbisida), Ekstrak Lantana camara 1%, 2%, dan 3%. Setiap perlakuan diulangi sebanyak tiga kali. Hasil penelitian menunjukkan bahwa Bioherbisida Lantana camara …

Pengendalian gulma dengan menggunakan herbisida tunggal tidak dapat mengendalikan berbagai jenis gulma, oleh karena itu perlu dilakukan pencampuran herbisida. Campuran herbisida dengan dua atau lebih jenis bahan aktif dapat bersifat sinergis, aditif, atau antagonis. Tujuan penelitian adalah untuk mengetahui sifat campuran herbisida IPA glifosat, imazetafir, dan karfentrazon-etil terhadap gulma daun lebar, gulma daun sempit, dan teki. Penelitian dilakukan pada Oktober 2018 sampai Januari 2019 di Laboratorium Kultur Terkendali Universitas Padjadjaran, Jatinangor. Perlakuan terdiri dari empat jenis herbisida dengan enam dosis, yaitu herbisida campuran IPA glifosat 380 g/L + imazetafir 40 g/L + karfentrazon-etil 8 g/L (dosis 2,000 L/ha; 1,000 L/ha; …

Palmer’s pigweed (Amaranthus palmeri) is a common grassland plant that occurs across much of North America. It is often considered a weed but is an important source of food for many game birds. We analyzed the energy content of seeds of Palmer’s pigweed obtained from the crops of scaled quail (Callipepla squamata) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were dried for 48 hours at 60°C to remove moisture and then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Palmer’s …
