  • Developmental Delay

    In H-LRT variety, minor developmental delay was observed when sulfosulfuron and ethoxysulfuron were applied POST at 150 and 200 g a.i. ha -1, respectively, but plants recovered upon maturity. [actahort.org]

  • Poor Growth

    Host plants are usually severely affected by the parasite, making poor growth and often not flowering. Crop yields are substantially reduced, causing major problems in areas where agriculture is already marginal or subject to drought. [bioref.lastdragon.org]

    Among them, various fungi such as Fusarium and Alternaria spp. and Myrothecium verrucaria [41] – [43] have been used successfully against Orobanche and Striga spp. [journals.plos.org]

Fresh and dried stem weight of tomato Stem fresh weight was affected by hand cutting and highest stem fresh weight (60.889 g/plant) was recorded in plots under hand cutting treatment. But, two other treatments had no differences. [regional.org.au]

Pre planting incorporated (PPI) treatments, excluding rimsulfuron, were more phytotoxic than POST application. All the POST and PPI applied herbicide treatments resulted in effective O. aegyptiaca control. [actahort.org]

Forms of the plant that are parasitic on sweet sage roots have been used as a treatment of cancer[257]. The dried and powdered plant is inserted in the rectum as a specific treatment for haemorrhoids[257]. [pfaf.org]

Treatment means were compared using least significant difference tests at a 5% level of probability. [journals.plos.org]

Etiology The causal organism Orobanche cernua Loefl. Var. desertorum Beck. is an annual, fleshy flowering plant, erect, 15-45 cm high. [agritech.tnau.ac.in]

Sanitary Methods Phytosanitation is aimed at preventing the spread of viable seeds by minimizing the movement of infested soil by farm machinery and vehicles, preventing grazing on infested plant material, treating manure (e.g. composting) and avoiding [plantwise.org]

Preventive measures are also important. Orobanche crenata was introduced in some countries in faba bean seeds infested by the weed seeds. [fao.org]

To prevent further Orobanche emergence, 3 g a.i. ha -1 of chlorsulfuron (Glean, DuPont, 75% WG), injected directly into the drip irrigation system at 28, 42, and 56 DAP is required. [actahort.org]
