Asian Crucifers

The term “Asian crucifers” is a broad category that encompasses Asian crucifer vegetables grown in the countries that comprise Asia and those eaten mainly by people of Asian extraction or who like Asian cuisine. Many of the Asian crucifers described in this chapter belong to the crucifer family, which is covered in depth in chapter 5, “Ethnic Vegetable Production.” However, there are still some overlaps between these two chapters.

This group of Asian crucifer vegetable species includes crops with edible leaves, like cabbage, broccoli, and bok choi, but also kohlrabi, which has edible swollen stems or tubers, and daikon, which is an edible root. These 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 chapter 2, “Fertilizer Management for Vegetable Production in Florida,” as general information. For pest-control products, these crops are included under this chapter, with the exception of daikon, for which refer to information on radish in chapter 15, “Root Crop Production.”

1 Mode of Action (MOA) codes for plant pest insecticides from the Insecticide Resistance Action Committee (IRAC) Mode of Action Classification v. 11.1 January 2024. Number codes are used to distinguish the main insecticide mode of action groups, with additional letters for certain subgroups within each main group. All insecticides within the same group (with same number) indicate the same active ingredient or similar mode of action. This information must be considered for the insecticide resistance management decisions. U = unknown, or a mode of action that has not been classified yet

2 Always double-check labels regarding maximum application limits. Many labels are changing from a maximum rate per season (or crop cycle) to a maximum rate per year.

The use of brand names and any mention or listing of commercial products or services in the publication does not imply endorsement by UF/IFAS Extension nor discrimination against similar products or services not mentioned.

Table 10. Cole crop fungicides ordered by disease and FRAC group according to mode of action. Cole crops include head and stem crops (broccoli, brussels sprout, cauliflower, Chinese broccoli, and Chinese cabbage); leafy crops (collards, kale, mustard, and turnip); and watercress. Labels change frequently. Be sure to read a current product label before applying any chemical. Please refer to chapter 19 for information on biopesticides, including materials labeled for certified organic production.

1 FRAC code (fungicide group): Numbers and letters are used to distinguish the fungicide mode of action groups. All fungicides within the same group (with same number or letter) indicate the same active ingredient or similar mode of action. This information must be considered for the fungicide resistance management decisions. P = host plant defense inducers. Source: FRAC Code List; https://www.frac.info/ (FRAC = Fungicide Resistance Action Committee).

2 Always double-check labels regarding maximum application limits. Many labels are changing from a maximum rate per season (or crop cycle) to a maximum rate per year.

Product

Application Directions

Mocap 15G

(a.i. ethoprop)

Apply 13 lb/A (36 in. row spacing) or 0.9 lb/1,000 linear row ft in a band of 15 in. wide on the row at-planting. Mix with the top 2–4 in. of soil with mechanical equipment right after application. If broadcast, apply 34 lb/A from 1 week before planting to at planting time and mix with 2–4 in. of soil. Do not use as a seed furrow treatment or allow granules to contact the seed. No more than 1 application per season.

Mocap EC

(a.i. ethoprop)

Apply in 12 to 15 in. band on the row and incorporate 2–4 in. deep immediately following treatment. Do not use as a seed furrow treatment or allow spray to contact the seed because phytotoxicity may occur.

Nimitz

(a.i. fluensulfone)

All applications must be incorporated either physically or via drip or overhead irrigation. Make preplant applications at a rate of 3.5–7 pt/A (56.0–80.0 fl oz/A) a minimum of 30 days before planting. Do not plant any unlisted crops into treated land for 365 days after application of the product. No more than 1 application per crop and no more than 112 fl oz/A per year (365 days). Provides control only for nematodes. Growers applying Nimitz must consult the product label to observe the plant-back (recropping) intervals for a variety of crops.

Velum

(a.i. fluopyram)

Apply max 6.84 fl oz/A using only chemigation into root-zone through low-pressure drip, trickle, microsprinkler, or equivalent equipment. Soil reapplications at least 5 days apart. No more than 13.7 fl oz/A of Velum (0.446 lb/A fluopyram) per year, regardless of formulation (Velum and/or Luna) or method of application (soil or foliar). For soil application, to limit the potential for development of disease resistance to this chemical class, the first foliar fungicide application after Velum should be a product from a different FRAC group.

Biological nematicides

See chapter 19.

Mocap is an insecticide/nematicide; Velum is a fungicide/nematicide; Nimitz is a true nematicide. Unlike fumigants, these products are not volatile and will move through the soil via water. Depending on the water solubility, these products will have different recommendations for how to best apply them (see specific label recommendations). When nematode pressure is high, they may not be as consistently effective against root nematodes as the fumigants.

1 Gallons/acre and fl oz/1000 ft provided only for mineral soils. Higher rates may be possible for heavier-textured (loam, silt, clay) or highly organic soils.

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 (GAPs), product and applicator training certification, and other rate-modifying recommendations.

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

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.
