Halosulfuron Injury on Cucurbit Crops | Scouting Guides for …
Halosulfuron (Sandea) injury. An herbicide labeled for use on many cucurbits (cucumbers, melons, pumpkins), halosulfuron controls many broadleaf weeds and nutsedge but not grasses. This herbicide can be applied pre-plant under plastic or …
Considerations for Mid-Season Weed Control in Cucurbits
2020年7月1日 · Herbicide Options: Row middles: If your vines have not grown into the row middles, a directed or hooded application can be made with broad-spectrum herbicides glyphosate (ie Roundup ®) or carfentrazone (ie Aim ®) (Figure 2). Avoid contacting the crop, which could result in crop injury or crop death.
Herbicide injury on garden plants | UMN Extension
Fruit, vegetable and ornamental plants can be injured by drift from herbicides that are sprayed on nearby lawns and crop fields to kill weeds. Herbicide injury symptoms depend on the herbicide applied and the garden plant species. Know how to identify herbicide injury and tell it apart from other plant problems like nutrient deficiency and ...
Effects of low-dose applications of 2,4-D and dicamba on cucumber …
Off-target movement of auxinic herbicides can be detrimental to cucumber and cantaloupe crops by causing visual injury, reducing vine growth, and negatively affecting yield. Furthermore, residue detection in marketable fruit can be devastating to growers …
Weed Interference and Management in Cucumber - IntechOpen
2021年10月6日 · Weed interference is a major problem in cucumber farming, leading to 45–95% yield reduction. Weed control practices employed to avoid such losses are predominantly hand weeding and herbicides application. All the weed control methods used in cucumber farming have their own limitations.

Varietal Tolerance of Cucurbitaceous Crops with
2024年6月1日 · Cucumber showed a greater response to S-metolachlor with up to 67% injury observed at 5.70 lb/acre. S-metolachlor applications to pumpkin and summer squash resulted in less than 6% injury, regardless of application rate or crop variety.
The cucumber is more susceptible to injury by several classes of selective herbicides than most other crops. All herbicides evaluated for weed control in cucumbers have a limited safety margin, and even at safe rates of application, the number of weeds they control varies with environmental conditions (1,4,5,-
Cucumber (Cucumis sativus L.), pumpkin (Cucurbita maxima Duch. ex Lam.), and summer squash (Cucurbita pepo L.) are economically important crops in Virginia. Only a few herbicides are registered for weed control in these crops. Halosulfuron is a sulfonylurea herbicide which controls several broadleaf weeds and yellow nutsedge (Cyperus esculentus ...
Drift of auxinic herbicides, such as 2,4-D, can cause considerable damage to nontarget crops. Exposure to 2,4-D stimulates ethylene formation, with higher production rates in sensitive plant species than in tolerant ones (Abeles, 1968; Tittle, 1990). The phytotoxicity of auxinic herbicides has been attributed to the accumulation of cyanide as a ...
