Goals and Challenges for Lettuce and Leafy Green growers

Lettuce, cabbage, spinach, kale, arugula, iceberg, collard greens...all of America's favorite leafy green fresh produce. These crops are produced organically and conventionally throughout the United States, but most commonly across California and Yuma, Arizona. . According to USDA, California leads the nation in vegetable production, accounting for 39% of the U.S. vegetable acreage. In 2020, the total output of leaf lettuce totaled 15.6 million cwt, up 25% from the previous year, with a planted area estimated at 62,900 acres an area harvested, at 61,700 acres. As for the head lettuce, the total production in 2020 was totaled 40.7 million cwt. The planted area slightly decreased over the previous year with an estimated at 114,000 acres versus an area harvested at 112,900 acres1.

The main goal of lettuce and leafy green growers is to produce a plentiful, healthy crop to bring in front of consumers to enjoy. Sounds easy, right? It turns out, lettuce and leafy greens are some of the most challenging crops to grow. The reason why can be summed up into two words PESTS and DISEASES. Controlling pests is very important to lettuce growers because the smallest insect bite or fungal discoloration can make the crop not suitable to picky human eyes. Some of the main pests in leafy green production include: lygus bug, cabbage aphid, thrips, aphids, whiteflies, and two-spotted spider mites. It is essential for growers to seek out different protection methods to prevent pests from damaging their crops. 

Lettuce and Leafy Greens in the Greenhouse

Aside from conventional outdoor production, there is a large sector of the industry producing lettuce indoors in greenhouses. Although indoors, greenhouse lettuce is also at risk for pest outbreaks. It is important to be able to provide a suitable environment for lettuce and leafy greens whether it is growing indoors our outdoors. Keming Crop Technologies has been recognized as a key provider of crop protection solutions to greenhouse growers in the articles below:

Gemsei™ (EPA registered) and AlliCURB™ (FIFRA 25(b) exempt, for use in California only) are OMRI-Listed, garlic oil-based, contact insecticides, miticides, and powerful repellents that control a wide range of pests, especially lepidopteran insects, on various crops.

The strong repellency and insecticidal activity of Gemsei and AlliCURB come from the garlic oil active ingredient that controls pests through multiple modes of action:  desiccation, antifeedant deterrent, mating disruption, and anti-oviposition activities,  limiting the likelihood of target pests developing pesticide resistance. They provide flexibility and convenience during harvest time as they have a 0-day PHI.
