Lab 4
Another successful and hopefully enjoyable week in lab has passed. Here are a few things you need to know from this week.
In lab this week you applied Gnatrol to your Easter lilies to control fungus gnat larvae. The rate was 32oz/100gal.
Our EC readings on the mums were much better this week. The leeching on Monday did it’s job. We will continue with the same concentration of fertilizer and check the EC again next week in lab.
A couple of observant students noticed aphids on their Easter lilies on Wednesday. Also there were quite a few thrips on at least one sticky card. Because of this we sprayed everything but the ferns and chives on Friday. A tank mix of Azatin and Decathlon was used. Azatin was used at the rate of 16oz/100gal. It is an insect growth regulator and will control the nymph stages of aphids and the pupal and larvel stages of thrips. Decthlon was also used at a rate of 1.9oz/100gal. It is a synthetic pyrethroid that will control the nymph and adult stages of aphids, adult and larval stages of thrips, as well as the adult stages of fungus gnats.
By popular demand the fertilizers and the crops they are used on are written on the whiteboard in the greenhouse. Greenhouse A is the section where your bench is. Greenhouse B is where you have been potting your plants.
On last thing. TAMU Vista has an email feature. It is only useful within Vista and does not forward to your NEO account. Be sure you are checking this for communications from your instructors. If you don’t know how to check it please stop by and see me for help.
