Spatial and temporal analysis of
Convolvulus arvensis L.
tabaci indicates that 1st adult of the year to appear almost after 3rd week of January, usually on
Convolvulus arvensis and Euphorbia spp., or cultivated plants such as Brassica spp., [3], and Echinochloa crus-galli L, Amaranthus retroflexus L, Solanum nigrum L.
Roncoroni noted that the pre-emergent herbicides aren't effective against field bindweed (
Convolvulus arvensis), which has very deep rhizomes.

Eight species namely Ageratum conyzoides, Parthenium hysterophorus, Amaranthus viridis, Chenopodium murale,
convolvulus arvensis, Brachiaria ramose, Cynodon dactylon and Dactyloctenium aegyptium exhibited 90% prevalence each Among others, 6 species namely Achyranthes aspera, Coronopus didymus, Cenchrus pennisetiformis, Dicanthium annulatum, Eragrostis poaeoides, Rumex dentatus, found in all the eight studied sites and showed 100% prevalence.
A total of twenty five frequently occurring weeds were sampled out of which seventeen Viz.,

Convolvulus arvensis, Poa annua and Oxalis corniculata were sampled for invertebrate fauna from sugarcane fields.
Summer annual weeds such as foxtail (Setaria spp.), pigweed (Amaranthus spp.) and lambsquarter (Chenopodium album) or perennial weeds such as field bindweed (
Convolvulus arvensis L.), curly dock (Rumex crispus L.), and dandelion (Taraxacum officinale Wigg.) are the most troublesome weed species found in many alfalfa fields.
These species were Arisaema jacquemontii, Artemisia japonica, Astragalus candolleanus, Berberis jaeschkeana, Chenopodium album,
Convolvulus arvensis, Corydalis govaniana, Jasminum humile, Raphanus sativus, Saussurea costus, Thymus linearis, Annona squamosa, Pupulia lappacea and Drosera peltata.
