Southwest Purdue Ag Center High Tunnel Tour Date: June 13, 2018 7:00-9:00 pm Eastern Time Location: Southwest Purdue Agricultural Center, 4369 North Purdue Road, Vincennes, IN, 47591 The SWPAC high tunnel tour will be held on the evening of June 13, 2018. Seedless cucumber production in high tunnels will be the highlight of this year’s event. You will see 16 cucumber varieties grown in a high tunnel, and be able to taste them. We will share with you yield results of grafted cucumber plants that have started to produce since middle April in an unheated high tunnel. You will also see cucumbers grown in the high tunnels with different pruning and trellising systems. Entomologist Laura Ingwell will join us at the event to discuss cucumber beetle management approaches. Other things you will see at this event include: summer squashes growing in a high tunnel; different pruning and trellising systems for growing tomato and pepper;[Read More…]

Three videos on in-row weeding tools (Finger weeder, Torsion weeder, Tine harrow) were developed at the Michigan State University Department of Horticulture. Each video is 20 minutes: introduces the tool, how it works, different models, show adjusting the tool in the field, and a short interview with a farmer who uses the tool. These videos can be accessed at the MSU Mechanical Weed Control Channel https://www.youtube.com/channel/UCH-k889oYbUaEznvgiDtrOQ
Bacterial wilt is one of the most destructive diseases in high tunnel cucumber production. The reason bacterial wilt is so important is because, like other wilt diseases, it ties up with the entire vascular system of a plant, causing systemic effects (Figure 1). The relatively less important roles that other cucumber diseases play also make bacterial wilt the major limitation for high tunnel cucumber production in Indiana. For example, common cucumber diseases such as angular leaf spot, anthracnose and Alternaria leaf blight seldom occur in a high tunnel scenario; improved resistance to powdery mildew was observed in some of the newly developed cucumber varieties; downy mildew in general does not occur in Indiana until end of the high tunnel cucumber production season. The causal organism for bacterial wilt of cucumbers is Erwinia tracheiphila. After the bacteria enter the plant vascular system, it multiplies quickly. As a result, it interferes with[Read More…]

This article provides more detailed information about this herbicide. How does Chateau® herbicide work Chateau® is a group 14 mode-of-action herbicide. Compounds in this group are most active on broadleaf weeds. Before Chateau® became available, no other preemergence herbicide with the same mode of action was labeled for use in watermelons and cantaloupes. The active ingredient of Chateau® herbicide, flumioxazin, controls susceptible weeds by inhibiting propoporphyrinogen oxidase (PPO), an enzyme that controls chlorophyll synthesis. Because of chlorophyll production inhibition, a chain reaction occurs within the plant that causes cell membrane disruption. Chateau® herbicide can assist in the postemergence control of emerged weeds. It is taken up by roots, stems, or leaves of young plants. It kills weeds through direct contact. There is usually little or no translocation of the herbicide within plants. Foliage necrosis can be observed after 4 to 6 hours of sunlight following the herbicide application. Susceptible plants[Read More…]
