Table grapes may be grown in many parts of the US, as well as throughout the world. European varieties (Vitis vinifera) and many hybrids grow best when the soil pH is between 6.0 and 7.0, but Vitis labrusca (Variety native to North America) varieties can tolerate a pH of 5.5 or slightly lower. California vines account for 99% of all US commercially grown table grapes, and the table grape vineyards cover more than 80,000 acres.
Pruning plants is an important management technique to encourage lateral growth, mitigate pest and disease pressure, as well as improve overall fruiting quality. The act of pruning can also pose a risk for the entry of bacteria and other pathogens to enter, compromising plant health. Spur Shield® is not a fungicide but rather a proprietary nature-based sealant. It creates a barrier against many wood pathogens that enter cuts and wounds assisted by rainfall. The combination of cleansing and sealing properties is especially effective in areas where the pruning season is cold and wet.
Spur Shield® is a Pinolene® based resin barrier that may be sprayed on pruning cuts and bark surfaces to seal wounds and inhibit water and bacteria from entering surface cuts.
Uniform fruit ripening, color development, and Brix accumulation can be affected by numerous factors such as photosynthesis, leaf age, nutrient deficiencies, and disease pressure. As plants begin to senesce, or age, closer to harvest, photosynthesis and metabolism may be reduced. This can lead to uneven ripening and poor sugar development. Sugar Express® applications provide key nutrients which help aid the normal photosynthetic processes which are the driver for Brix development. The accumulation of Brix earlier may improve ripening and color which is necessary for uniform quality. The addition of Calcium Chelate at this time can also assist in improving development and fruit firmness through the strengthening of cellular structure.
Sugar Express® 4-10-40 is a highly refined fertilizer with the appropriate ratio of phosphorus and potassium designed to be used close to harvest.
Typically, systemic chemistries are utilized to expedite the process of bud break. By incorporating Exit® into this application mix, the proprietary humectant system and unique delivery system allow for an enhanced speed of uptake as well as overall uptake efficiency. Exit was designed to be able to penetrate plant tissue, which is especially critical in woody plant tissue, as is found in grapes.
Exit® is an activator-adjuvant comprising a blend of premium-quality esterified seed oil with a proprietary surfactant and humectant system.
Diseases such as powdery mildew can compromise the health of your crop and its productivity. Sulforix® is a contact pesticide capable of controlling various types of pests. Calcium polysulfide is a caustic solution that penetrates and controls various types of pests and disease, such as powdery mildew. The proprietary spreader penetrant technology in this product increases the speed and consistency of penetration, which can improve efficacy.
Sulforix® is an EPA-registered fungicide, insecticide, and miticide with unique penetration properties.
During periods of rapid growth, fruit development and ripening, plants require energy for proper physiological development and high levels of calcium for fruit quality. Physiological and environmental crop stress slows down plant metabolism and the movement of calcium within plant tissue. Consequently, plants suffer, and crop development is weakened, while fruit frequently lacks the necessary nutrients (including calcium) required for optimum harvest quality. Calexin® translocates through the phloem and xylem increasing calcium mobilization to fruit while supporting natural color development.
Calexin® is a translaminar calcium formulation which works to supplement with the plant's natural ripening and coloring stages.
