Asian Crucifers

The term "Asian vegetables" is a broad category which encompasses both the vegetables grown in the countries that comprise Asia and those eaten mainly by people of Asian extraction or who like Asian cuisine. Since many of the Asian vegetables which are described in this chapter are members of correspondent families that are covered in depth in other chapters in this volume, that information will nto be duplicated.

This group of vegetables include crops with edible leaves like cabbage, broccoli, mustard but also kohlrabi, with an edible swollen stem and daikon which is an edible root. The crops can be grown on raised beds with or without mulch and with drip, overhead or subsurface irrigation. Fertilizer recommendations for these crops can be found in under broccoli, cabbage or Chinese cabbage section. For pest control products, these crops are included under this chapter, with the exception of daikon.

Number codes (1 through 29) are used to distinguish the main insecticide mode of action groups, with additional letters for certain sub-groups within each main group. All insecticides within the same group (with same number) indicate same active ingredient or similar mode of action. This information must be considered for the insecticide resistance management decisions. - = unknown, or a mode of action that has not been classified yet.

1 FRAC code (fungicide group): Number (1 through 46) and letters (U and P) are used to distinguish the fungicide mode of action groups. All fungicides within the same group (with same number or letter) indicate same active ingredient or similar mode of action. This information must be considered for the fungicide resistance management decisions. U = unknown, or a mode of action that has not been classified yet and is typically associated with another number; P = host plant defense inducers.

2 All of the fumigants mentioned are for retail sale and use only by state certified applicators or persons under their direct supervision. New supplemental labeling for the Telone products must be in the hands of the user at the time of application. See new product label details for additional use restrictions based on soil characteristics, buffer zones, requirements for Personal Protective Equipment (PPE), mandatory good agricultural practices (GAP’s), product and applicator training certification, and other rate modifying recommendations.

3 Higher application rates are possible in the presence of cyst-forming nematodes.

4 Rates are believed to be correct for products named, and similar products of other brand names, when applied to mineral soils. Higher rates are required for muck (organic) soils. However, the grower has the final responsibility to see that each product is used legally; read the label of the product to be sure that you are using it properly.
