For many of us, this time of year is tough for our zucchini, squash and pumpkin plants. A close inspection of wilting plants may reveal a sawdust-like substance around the soil surface or on the base of the stem. When pushed, the plants typically break and reveal clear evidence of insect feeding through the stem.

Ripe fruit that has been injured as well as ground fall fruits often attract undesirable insects into an area.

There are 24 million acres of native and tame pasture and range as well as 1.4 million acres of grass hayland in South Dakota.

Noxious Weed Recommendations: Herbicides for pasture, range, and non-crop areas, including roadside and other right-of-way that may be harvested for hay or grazed, are given a priority.
Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.
There are currently millions acres across South Dakota impacted by saline and sodic conditions. Research has shown that salt-tolerant perennial grasses are a possible way to bring land back into production.
The alfalfa weevil is a major spring insect pest of South Dakota alfalfa. Before 2018, this insect was reported as having large populations throughout much of South Dakota. However, during 2018 and 2019, we received fewer reports of alfalfa weevils, which may have been a result of the cooler and wetter spring conditions that were observed.
