These soil dwelling primitive insects primarily attack germinating lettuce seeds and young plants, reducing the plant vigor or cause death, which cause patchy or area-wide stand loss. Most springtails possess a forked organ (furcula) in the rear-end, which is extended forward and backward to jump (Fig. 1); hence, the common name, springtail. However, the springtail species,...

Maggots are the larval stages of true flies (Order Diptera). In the Salinas Valley, broccoli and cauliflower are grown in 28,328 Ha mostly in rotation with lettuce. Root maggots mostly infest roots (Fig. 1a), but if the population pressure is severe, they could even attack the floret/flower head (Fig. 1b). Cauliflower is a...

The production of cilantro has shifted to high density 80-inch wide beds and a large proportion is now mechanically harvested. Hand weeding high density beds is very expensive and reduces the economic viability of this crop. As a result, there is a need for excellent weed control. Two broadleaf herbicides were registered on cilantro: Prefar and Caparol. Prefar was registered for a number of years and provides good...

In particular, early confirmations have been made of the Tomato Spotted Wilt Virus (TSWV) on lettuce in this region. Affected leaves have tan, brown, or blackish spots and dead areas; this necrotic tissue can resemble damage caused by pesticide or fertilizer applications (see photos below). Some leaf yellowing can also be observed. If...

Koike) http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=9649 Removing weeds from the seedline is the most difficult part of weed control for many of the vegetable crops that are grown on the Central Coast. Standard cultivation removes weeds in about 80% of the bed, but leaves a band 4 inches wide around the seedline. In conventional production the seedline is treated with preemergent herbicides which can significantly reduce weed pressure; however, uncontrolled weeds are removed by hand and weeding costs vary depending on the density of weeds and the...

Frost damage can often occur during the cold, clear nights in the winter and spring. Interestingly, frost damage on lettuce causes some classic symptoms that are easily recognizable and some that are a bit surprising. Different types of symptoms can be caused due to differences in the severity and duration of low temperatures, as well as the age and location of the leaf tissue. One of the more common symptoms of...

Like any other true bug, lygus bug has a piercing and sucking mouth part which appears as a snout-like structure or beak on the head. Within the beak, four stylets are housed which come out while the bug feeds on the plant. In the process, stylets puncture the cells and leave a feeding sheath within the plant (Figure 1a and b). As time progresses, these injured tissues, depending on the severity, turn into sunken or...

The defect is not caused by a disease or virus. It often occurs in areas on the fruit that rested against a branch (Photo 2) and appears to be the result of compression or rubbing. However, it can also occur on other parts of the fruit not associated with compression (Photo 3) and the reason for this is not entirely clear. At first glance, it seems to be the result of insect feeding. Thrips...
