Supply has been spotty as many later plantings matured earlier than expected. Some rain last weekend brought only a little respite from the severe drought we are experiencing but also brought a small wave of corn earworm and fall armyworm to many sites, threatening any corn that is at the silk stage or younger.<\/p>\n<p><strong>European corn borer<\/strong>: No moths were captured at the sites where we still have traps set up.<\/p>\n<p><strong>Corn earworm<\/strong>: Moth numbers were higher at all locations this week, with the exception of Oxford, probably as a result of last weekend\u2019s storm system. A five-day spray interval was recommended for Biddeford, Bowdoinham, Corinth, Dayton, Monmouth and Wayne; a four-day spray interval was recommended for Cape Elizabeth and Wells.<\/p>\n<p><strong>Fall armyworm<\/strong>: Moth counts in pheromone traps exceeded the control threshold (3) for silking corn in Biddeford, Bowdoinham, Cape Elizabeth, Corinth, Monmouth, Corinth, and one Wells site. All sites are under a spray schedule for earworm, so no additional sprays were recommended.<\/p>\n<p><strong>Western Bean Cutworm<\/strong>: No moths were caught this week.<\/p>\n<p><strong>Aphids<\/strong>: Aphid infestations on tassels and silks continue to be an issue in most fields. If sooty mold is becoming an issue on husks, sprays targeting aphids should be considered. Insecticides registered for aphids on corn include Assail\u00ae, Asana\u00ae, Warrior\u00ae and Lannate\u00ae.<\/p>\n<figure id=\"4792\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4792\" src=\"https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection-225x300.jpg\" alt=\"Soil Sample Collection\" width=\"225\" height=\"300\" srcset=\"https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection-225x300.jpg 225w, https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection-105x140.jpg 105w, https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection-317x423.jpg 317w, https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection-423x564.jpg 423w, https:\/\/extension.umaine.edu\/highmoor\/wp-content\/uploads\/sites\/48\/2015\/09\/Soil-Sample-Collection.jpg 480w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,225px\" \/><figcaption class=\"wp-caption-text\">Soil Sample Collection, photo by David Handley<\/figcaption><\/figure>\n<p><strong>It&#8217;s Soil Testing Time<\/strong>: Early fall is a good time to seed cover crops and is also a great time to take soil samples. Getting your soil tests results before the ground freezes allows time to correct soil pH with additions of lime, and to incorporate any needed nutrients into the soil, such as phosphorus, potassium, or magnesium, and to apply manure to increase organic matter. Fall applications of lime and nutrients (not nitrogen, as it is prone to leaching) are often ideal, because the fields are drier than in the spring, making applications easier, and nutrients will have time to reach the root zone before the plants need them. You can pick up soil test boxes and forms at any county office of the University of Maine Cooperative Extension, or call us here at Highmoor Farm if you\u2019d like us to send you some.
