Tobacco Transplants in the greenhouse
We’ve begun scouting in some our sites for this field season! It’s warming up outside and we are excited to get back in the field and share our scouting reports from around the state. This year we will have three sites in the eastern portion of the state and three sites from the Piedmont area. This week we visited two sites in Eastern NC, but starting next week we will be visiting all of the fields that are part of the scouting project this summer.
This year, will again be comparing grower standard management practices to management based on insect scouting. The goal of this project is to improve our scouting recommendations and make them easier for more growers to use. For more about the project, see our first scouting report from last year. Details about the scouting methods we use.
So far we have only seen flea beetles and some alate “winged” aphids, but most of the insects we observed were actually dead. This suggests that the greenhouse treatments are proving effective even though pest pressure is generally low this soon after transplant. These alate aphids are able to disperse into the field from much greater distances and are the first aphid colonizers in the field. Tobacco flea beetles overwinter in the soil and begin to emerge in the field as the weather becomes more favorable.
