The whitefly's biological cycle is monitored by the Valencia Plant Health Service. The pest spent the winter in advanced states of larvae turning into pupae on citrus leaves.
From the beginning of April, insects appeared on adult citrus fruits and transferred to persimmon flowering areas where adults and eggs are observed. This will give rise to the first generation.
Currently, there are about 1,500 varieties of persimmons. A species is growing in Africa whose fruits are dark red in color and about 3 cm in diameter.
This is a good time to use D. citri eggs to control them in combination with the first persimmon spotting treatment, Plurivorosphaerella nawae Mycosphaerella, for 10% pyrinoxifene. Treatment against this pest can also be performed by coinciding with the third leaf spot treatment, stage L1 - L2 whiteflies, with the active ingredients spiro tetramate 10% SC in volume and allowed paraffin oil.
Therefore, in those areas that suffered significant damage during the last campaign, it is recommended to consider the possibility of intervention depending on the observed levels of pests. The biological cycle will be monitored to determine future generations.
- Torrential rains caused serious damage to crops in Alicante and Murcia, which significantly reduced production volumes.
- In Spain, durum wheat prices continue to rise, while the value of other cereals is declining. According to the report of the Association of Trade in Grain and Oilseeds of Spain, in February 2020, against the backdrop of rising prices for durum wheat, a steady decline in the cost of wheat of other varieties, barley and corn was noted.
- A team of researchers from Cartagena Polytechnic University (UPCT) has developed an active container that can extend the shelf life of vegetables contained in it by more than 40%, significantly reducing the percentage of rotting fruits.
