Evaluation Of Pheromone Mating Disruption For California Red Scale Control In Commercial California Citrus, Joel Timothy Leonard
Evaluation Of Pheromone Mating Disruption For California Red Scale Control In Commercial California Citrus, Joel Timothy Leonard
Master's Theses
California red scale (CRS), Aonidella aurantii, is an increasingly injurious insect pest for the California citrus industry due to insecticide resistance, changing weather patterns, and shifting trade regulations. The presence of the insect on fruit, damages the rind of the fruit and high populations can cause dieback of branches as well as lower yields. Pheromone mating disruption of CRS has the potential to alleviate population control concerns and reduce insecticide use. The efficacy of the pheromone mating disruption technique for pest management of CRS was determined using the products CheckMate® CRS and Semios CRS Plus. CheckMate® CRS was evaluated …
Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley
Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley
Graduate Theses/Dissertations
Dicamba is a synthetic auxin herbicide which acts systematically and selectively controls broadleaf plants and has become increasingly popular in the past several years for weed control in commercial agriculture following widespread adoption of dicamba-resistant, transgenic soybean and cotton. Dicamba may be better acknowledged by growers of specialty crops, like grapes, for its capacity to drift miles away from the site of application and deposit on fields, remaining potent enough to cause crop damage and yield loss to vulnerable plants. Grapes are among the most susceptible agronomic crops to dicamba drift, showing visible injury at rates less than 1% of …
Pemanfaatan Fenomena Pembentukan Buah Partenokarpi Dalam Perspektif Pertanian Di Indonesia, Firman Rezaldi, Muhammad Abdilah Hasan Qonit, Anne Nuraini, Kusumiyati, Syariful Mubarok
Pemanfaatan Fenomena Pembentukan Buah Partenokarpi Dalam Perspektif Pertanian Di Indonesia, Firman Rezaldi, Muhammad Abdilah Hasan Qonit, Anne Nuraini, Kusumiyati, Syariful Mubarok
Jurnal Kultivasi
Buah merupakan organ reproduktif yang memainkan peranan penting pada tanaman dalam proses perbanyakan tanaman dan penyebaran biji. Biji akan terbentuk akibat adanya proses polinasi dan fertilisasi. Pada beberapa jenis buah keberadaan biji tidak diinginkan, sehingga sekarang sudah banyak dikembangkan buah tanpa biji atau buah partenokarpi. Secara garis besar partenokarpi terdiri dari dua kelompok utama, yaitu partenokarpi alami dan partenokarpi buatan. Pisang, tomat, dan manggis merupakan contoh tanaman yang bersifat partenokarpi alami. Pembetukan buah partenokarpi dapat dilakukan melalui beberapa cara diantaranya adalah penggunaan hormone auksin/giberelin, iridiasi polen, perubahan jumlah kromosom, gene silencing, modifikasi gen, dan genome editing tools. Review ini menjelaskan …
Identifying Consumer Perceptions Of Fresh-Market Blackberries, Aubrey Dunteman
Identifying Consumer Perceptions Of Fresh-Market Blackberries, Aubrey Dunteman
Food Science Undergraduate Honors Theses
Blackberries are grown worldwide for commercial fresh markets, but there is limited information on consumer perceptions of this fruit. In this study, physiochemical and consumer sensory attributes of three Arkansas-grown fresh-market blackberry genotypes were evaluated and consumer perceptions of fresh-market blackberries were also investigated though an online survey. Two cultivars (Natchez and Ouachita) and one advanced selection (A-2418) were evaluated for compositional and nutraceutical analysis and consumer sensory analysis. Natchez had the highest berry weight, length, drupelets and pyrenes/berry, and pyrene weight/berry. Ouachita had the highest soluble solids content (11.9%), pH (3.18) and soluble solids/titratable acidity ratio (10.92). There were …
Evaluation Of Host Resistance And The Utilization Of Organic Amendments To Manage Macrophomina Crown Rot Of Strawberry In California, Jonathan W. Winslow
Evaluation Of Host Resistance And The Utilization Of Organic Amendments To Manage Macrophomina Crown Rot Of Strawberry In California, Jonathan W. Winslow
Master's Theses
The production of strawberries can be severely limited by soilborne plant pathogens, insects and weeds. Macrophomina phaseolina is a problematic soilborne fungal pathogen in California strawberry production inciting the disease Macrophomina crown rot. When established, the pathogen can cause extensive plant decline and mortality. Host resistance will be a critical tool for managing this disease and guiding breeding programs in the post methyl bromide era. Evaluation of host resistance in strawberry germplasm to M. phaseolina was evaluated through phenotypic assessments of disease incidence. A total of 90 strawberry cultivars and elite selections were included in a replicated field trial conducted …
The Survival Of Mediterranean Fruit Fly (Diptera: Tephritidae) Over Winter In Western Australia, Touhidur Rahman, Sonya Broughton
The Survival Of Mediterranean Fruit Fly (Diptera: Tephritidae) Over Winter In Western Australia, Touhidur Rahman, Sonya Broughton
Biosecurity Research Articles
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the most economically important pest insects of fruit crops worldwide. Mediterranean fruit fly can cause up to 100% crop loss in susceptible fruit. In order to formulate best management practices, it is critical to understand how Mediterranean fruit fly overwinters in a given geographical location and bridge the gap between autumn and spring populations. In this study, we evaluated the overwintering potential of Mediterranean fruit fly immature and adult stages in two locations in Perth Hills, Western Australia. We also monitored wild adult Mediterranean fruit fly populations for …

Identifikasi Keanekaragaman Dan Dominansi Gulma Pada Lahan Pertanaman Jeruk (Citrus Sp.), Isna Tustiyani, Desember Risa Nurjanah, Siti Syarah Maesyaroh, Jenal Mutakin
Jurnal Kultivasi
Gulma merupakan tumbuhan yang mengganggu tanaman budidaya. Penelitian bertujuan untuk mengidentifikasi keanekaragaman dan dominansi gulma pada lahan pertanaman jeruk (Citrus sp.) di dataran medium Kabupaten Garut. Penelitian dilaksanakan pada Bulan April sampai Juni 2018. Metode penelitian adalah statistik kualitatif melalui studi kasus. Pengambilan sampel dilakukan pada 5 plot yang berbeda dengan luas pengambilan sempel gulma masing-masing 50 cm x 50 cm / plot. Setiap lahan terdapat 5 titik pengambilan sampel. Setelah didapatkan sampel gulma, maka dilakukan identifikasi gulma dan Summed Dominance Ratio. Hasil penelitian teridentifikasi 6 jenis gulma rumput, 3 gulma teki dan 13 jenis gulma daun lebar dengan indeks …
