SWEETPOTATO WHITEFLY CONTROL WITH NEONICOTINOIDS APPLIED THROUGH DRIP IRRIGATION ON CANTALOUPES, FALL 2005

Using Irrigation to Manage Weeds: A Focus on Drip Irrigation

Application of alternative fumigants through drip irrigation systems.

ABSTRACT Strawberry fields in California (9,500 ha annually) are pre-plant fumigated with methyl bromide and chloropicrin to prevent serious soil pest and disease problems. Although soil fumigation with methyl bromide has ensured stability of strawberry production, its use is being discontinued because of its effect on stratospheric ozone. The likely short-term alternatives such as 1,3-dichloro...

Effect of application variables on emissions and distribution of fumigants applied via subsurface drip irrigation.

Soil fumigation is useful for controlling soil-borne pests and diseases in high-cash-value crops. Fumigants are highly volatile, and approaches to reduce atmospheric emissions are required to protect human and environmental health. Application of fumigants through drip irrigation has been proposed as a means to decrease fumigant emissions, improve fumigant distribution in soil, and minimize wor...

Honeydew Production by Sweetpotato Whitefly Adults and Nymphs

We determined honeydew production by male and female sweetpotato whiteflies and the effects of temperature on honeydew production of each sex. We also determined honeydew production by each nymphal instar. Overall, adult SPW produced more honeydew than nymphs. Adult females produced more honeydew than males. The relative differences between honeydew production for males and females and between ...

Genome sequencing of the sweetpotato whitefly Bemisia tabaci MED/Q

The sweetpotato whitefly Bemisia tabaci is a highly destructive agricultural and ornamental crop pest. It damages host plants through both phloem feeding and vectoring plant pathogens. Introductions of B. tabaci are difficult to quarantine and eradicate because of its high reproductive rates, broad host plant range, and insecticide resistance. A total of 791 Gb of raw DNA sequence from whole ge...
