Digitaria spp

Study 2. The effects of wheat, oats, barley and rye mulches on three broadleaf weed species and crabgrass (Digitaria spp.) are shown in Table VI. Weed control data for the corn test at Kinston are not presented because of poor cover crop kill by the paraquat treatment.

Digitaria spp. and Panicum spp. are tolerant in all stages of development Echinocloa crus galli is tolerant in the seedling stage and in stages beyond the 3-4-leaf stage. 

Chlornidin is used as selective preemergence herbicide in cotton and soybean, for the control of Sorghum halepense, Amaranthus spp. and Digitaria spp. (Talbert,... 

Terbutol is mainly a soil herbicide, but it is also effective postemergence for the control of grass weeds. It has a selective action in cotton, maize, tomato and soybean, and is recommended for the control of crab grass in established turf. It is particularly effective for the control of Digitaria spp. 

Even the most active representative of the N-phenylcarbamates contained in the table, propham, is inactive to millet Panicum spp.) and to Digitaria spp. 

Chlorpropham is effective for the control of several grass weeds (Digitaria spp., Agropyron spp., etc.) for which propham is ineffective. 

DMPA is a preemergence soil herbicide which has been used in turf for the control of crab grass Digitaria spp.), and in soybeans, peas, beans and onions against grass weeds (Roberts et ai, 1966), but it has been superseded today. 

Digitaria spp. (family Gramineae) - Digitaria exilis and D. iburica are... 

Panicum miliaceum (family Gramineae) Commonly known as common millet and distributed in eastern and southern Asia, Africa and the Mediterranean region. It is a short-duration crop containing about 18% protein and can be used for similar products as the Digitaria spp. 

One of the features of allelopathy, as pointed out by Rice (18). is that it is specific. Certain species, but not others, are affected by the allelochemics produced by a plant. This suggests that allelopathy by a weed must be positively demonstrated for each crop. References to specific reports of demonstrated allelopathy by a weed on a crop are given in Table 1. In some cases [crabgrass (Digitaria sanguinalis (L.) Scop.), spurge (Euphorbia spp.), etc.], no crop is listed in the allelopathy column.
