Binh Phuoc: The impact of weather on cashew yield is negligible

In recent times, the weather has fluctuated, the province has appeared many rainy season and fog in the early morning. This phenomena occurs at the time when the cashew is flowering flowers affect the flowering, pollinating process; Some areas are hit by cotton pests.

However, the survey and evaluation of the agricultural sector, on a large scale, the impact of weather on cashew yield is negligible, even where rainfall is not expected to yield higher than last year. Particularly for areas affected by rain, the level of yield reduction effect is estimated at 5 - 10% compared to the case in 2016 (depending on the time of pollination of each garden).

Through reflection of the local area of ​​cashew dried, dry fruit is mainly due to anthracnose and mosquito bite extract damage, reducing the yield of cashew. At present, the anthracnose disease in cashew trees occupies a large area of ​​4,073 ha, mainly causing damage in Phu Rieng districts: 1.879 ha, Bu Gia Map 838 ha, Dong Phu 307 ha, Bu Dang 256 ha. Tea mosquito bugs caused damage to 3,627 ha of cashewnut, mainly in Phu Rieng district with 1,076 ha, 583 ha in Bu Gia Map district, 560 ha in Phuoc Long town, and 256 hectares in Bu Dang.

The level of harm of these two subjects from mild to moderate. However, some areas are harmed locally with the level of damage up to 30-35% of productivity in some areas such as Phu Nghia (Bu Gia Map) 200 ha. In Phu Rieng district, mosquito bugs caused serious damage to 129 ha, mainly in Phu Trung, Phu Rieng, Long Ha and Phuoc Tan communes.

Apart from the anthracnose, tea mosquito bugs and some other infested plants, at this stage, red caterpillars have also emerged and caused relatively widespread harm. Through surveys and data collected from communes in the province, the total area of ​​the red-tailed macaque was 55 hectares, with heavy losses in Phuoc Tan, 11 hectares, Phu Rieng 9 hectares and Phu Trung 7. Ha, Long Ha 6 ha, Long Tan 5 ha.

Facing with this situation, the Department of Agriculture and Rural Development has worked with the Cultivation Department, the Plant Protection Department, the Southern Institute of Agricultural Sciences and the Center for Plant Protection in the South (Ministry of Agriculture and Rural Development). Rural development) to survey the actual pest and disease situation in most cashew areas in the province. Through this assessment and assessment, pest and disease situation is well managed. However, with the current weather patterns (heavy rain, high humidity), the outbreak of disease in the crop is quite high. Farmers must regularly visit the garden for timely detection and prevention plans.
