mineral oil???sweet corn???
Comments (21)Anney: mostly just curiosity but also, one year I went to spray Bt and realized I was out. Living an hour's drive from the nearest source, it was just a bit of a pain in the a** to quickly go get some. An alternative close at hand would have been nice. Also, my sprayer is a bit unwieldy and a small bottle with a dropper might be even handier. I wonder if Stylet Oil would work as well, it isn't labeled for sweetcorn, just field corn for Fall armyworm. Too bad. Thanks Anney, I think I'll do a half and half (oil on one half/Bt on the other) and see what happens. Michael...See Moreupdates on bt sweet corn
Comments (2)I have only grown BT sweetcorn for the last 4 years. The triple sweet gene makes it the sweetest and most flavorful corn on the market. You can buy it without the BT gene if you like...I have never received more positive compliments from my customers. It is 100% corn borer free. No smuts no lodging no broken stalks or stalk rots. You should not get any earworms except some survive eating down the silk tunnel and die by the time they get to the first tip kernel. The plants are attacked by fall armyworms which we don't see until September in NJ because the BT toxin is not very strong. I don't have to apply any pesticide to BT corn June thru labor day and by not spraying every three days like you do with regular sweetcorn the beneficial pests take over and control the other pests in corn...

Comments (3)According to the Burpee website, you chose a sugar enhanced variety so I am surprised it wasn't sweet. I'm a fan of Johnny's Seeds which has a website comparison of sugary enhanced corn varieties which shows comments on flavors. That's why I like a seed source like Johnny's which gives more information. We don't grow corn anymore because the raccoons always knew it was ready the night before we did. I buy from local farmstands. But whenever flavor doesn't seem good enough, I suspect not enough fertility. Agway farm and feed stores have a great selection of seeds from several companies. Do you have one in your area? Here is a link that might be useful: corn comparison...See MoreSweet corn variety
Comments (17)Kinglerch, SH2 corns will cross-pollinate with every other corn plant grown, so you can't have two pollinating in your garden at the same time. In fact, many community gardens have banned their members from growing SH2 types because they will cross-pollinate (and ruin) every other corn grown in the community garden. In theory, you can grow two or more SH2 corns in the same garden in the same year, but it is hard to do it successfully and it requires that the weather be cooperative too. You have to time the plantings so the two (or more) varieties are NOT pollinating at the same time, because they can cross-pollinate each other. Timing of the plantings means more than just planting one SH2 corn, waiting 2 to 4 weeks, and then planting another SH2 corn. Why? Because the earlier planting is done when both soil and air temps. are cooler, so the corn germinates more slowly and then grows more slowly as well. When you plant the second SH2 corn, it is planted in warmer air and soil temps., so it will germinate more quickly and also grow more quickly as well. So, often the second planting "catches up" with the first and they pollinate at exactly the same time despite your best efforts to prevent that from happening. You can sometimes get around that by learning about heat units in relation to corn production and then timing your corn plantings based on heat units. That is how commercial corn growers do it. You can sometimes plant two SH2 corn varieties by planting them at least 250' from each other, which is possible if you have acreage. You can sometimes plant two SH2 corn varieties and NOT have cross-pollination if you plant a barrier crop between them. It has to be something big and thick like sunflowers or amaranth or something similar. With careful timing of the fall planting, you can get 2 SH2 corn crops in the same year without cross-pollination by planting one in March-April for harvest in June or early July and then planting the second type in late July to mid-August for harvest in October or November. That works for me here in zone 7B. Dawn...See Moreanniew
