Pest Management

Navel orangeworm (NOW), Amyelois transitella, first appeared in California in the early half of the 20th century and rapidly increased. Currently, navel orangeworm is the primary pest of almonds, pistachios and walnuts, and also present in citrus, stone fruit, pome, date, and fig crops, impacting the dynamics of the pest in California as hosts for the pest. This course discusses the threat of navel orangeworm in nut crops, as well as best management practices for treatment.

This course is accredited for the following licensing categories: PCAs, Qualified Applicators, Private Applicators, Aerial Applicators, and County Permit Holders.

This course will provide an overview of several areas that are key to pesticide safety and application. We will cover subjects such as types of licenses, Personal Protective Equipment (PPE), labeling and label interpretations, application equipment and techniques, first aid and decontamination procedures, and Integrated Pest Management (IPM) and techniques. It is critical that the fundamentals are taught and reviewed regularly by all applicators and advisers.

As of January 2018, there were approximately 2.63 million managed honey bee colonies in the U.S. Over 500,000 make their home permanently in California, while another 1.5 million hives are moved into the state annually to augment the pollination demands of California’s almond crop alone. This means slightly fewer than 79 percent of the managed hives in the U.S. are used to pollinate a single California crop.

In 2019 there are about 1.16 million planted acres of almond orchards in California, with mature trees on bearing acreages capable of producing more than 2.27 billion pounds of almonds annually. Growers usually rent two colonies of honey bees per bearing acre.

“Honey bees are essential to almond production,” said Bob Curtis, pollination consultant and retired director of Agricultural Affairs for the Almond Board of California. “Every almond we eat exists because a honey bee pollinated an almond blossom so it’s in farmers’ best interest to keep them safe. Our livelihood depends on it.”

As important as managed honey bees are to almonds and the more than 100 other crops they pollinate, pesticides and insecticides used to protect crops against pests are also important. Farmers and crop protection specialists recognize that and work diligently to ensure that pollinators and pesticides can co-exist in balance.

This course will examine the stressors on the honey bee population such as Colony Collapse Disorder, nutrition, pesticides, parasites and pathogens as well as rules and legislation to protect honey bees. 

This course discusses mite control in major crops and is sponsored by BASF. Mites are small arthropods in the class Arachnida and the subclass Acari. Although they are related to insects, mites are in the arachnid class and are closely related to spiders and ticks. They are common pests in agriculture, landscapes, and gardens. Mite species are estimated to number nearly 50,000. They live in diverse habitats; in soil, water or plant matter. They eat living and dead plant material as well as fungi, lichens, and even carrion. Some are parasites on animals and others feed on mold. This course will focus on the mites that threaten nut trees, pome fruit, grape, strawberry, tomato, and citrus crops.

Almonds are California's number one agricultural export and the number one U.S. horticultural export. The first record of an almond orchard in California dates back to 1843. They were grown in the foothills of the Sacramento Valley. By the mid-1920s, one of these seedlings, the Nonpareil variety, had become established as the industry standard in the marketplace and in the orchard. Once proven, the almond industry grew steadily, and by the mid-1950s there were approximately 100,000 acres of orchard trees under cultivation. A period of rapid growth followed in the 1960s, '70s and early '80s and, now, there are approximately 750,000 bearing acres of almonds in the state. Non-bearing acreage totals 825,000 acres. Recent annual crops are estimated at almost two billion pounds. This course is sponsored by Western Farm Press and its purpose is to provide a review of some insects and mites that impact California almonds as well as some practical information on ways to mitigate orchard damage.

This course is sponsored by Western Farm Press. There are an estimated 150,000 named species in the insect group called Lepidoptera. Outnumbered only by the beetles, Lepidoptera represent the second-most diverse order of insect pests, and virtually every cultivated plant is attacked by at least one type. They are ready to defoliate and weaken plants or mine plant tissues, leaving holes and frass behind and rendering crops unmarketable. Their scientific name comes from the Greek Lepidos, for “scale,” and Pteron, for “wing”--literally “scale wing,”--because the wings of adult butterflies and moths are covered with microscopic scales. This course will specifically highlight six lepidopterous pests: the beet armyworm, cabbage looper, diamondback moth, tomato fruitworm, tomato pinworm and western yellowstriped armyworm. The course will also cover managing Lepidopterous pests in a wide array of crops and includes an additional section on Pesticide Safety.

Biopesticides are increasingly being recommended as components of Integrated Pest Management (IPM) programs in the production of non-organic high-value specialty crops like fruit, nut, vegetable, vine, ornamental and turf. There are about 430 registered biopesticide active ingredients used in a wide array of agricultural pest management products. Biopesticides are derived from natural materials such as animals, plants, bacteria, and certain minerals. Biopesticides are considered an effective pest control option for organic crop production. However, they increasingly are being recommended and used as components of Integrated Pest Management (IPM) programs in the production of non-organic high-value specialty crops such as fruit, nut, vegetable, vine, ornamental, and turf. This online CE course covers the principles for using the 430+ registered biopesticide active ingredients used in a wide array of agricultural pest management products. It is sponsored by Marrone Bio Innovations and includes a Safety Review at the conclusion of the course material.

Western Farm Press is pleased to sponsor this course on ant control, which is an important element of harvesting a high quality almond crop. More than 800,000 acres in the San Joaquin and Sacramento valleys are under almond cultivation. Almonds are the largest U.S. specialty export crop and the top agricultural export of the state of California. Protecting this highly valuable crop is a high priority each year. This course focuses on ant management and broadleaf weed control in California almonds. The two subjects are combined because they work together when it comes to protecting newly harvested almonds from ant damage. Ants feed on ground cover and in order to control ants, a grower and/or his PCA must create an environment where ants can be drawn to ant bait.
