From December last year to January this year, several large-scale cold wave weather had a greater impact on open-field vegetables, and some of them showed curling, wilting, black hair and yellow hair
.
All production bases strengthened the cold and warm protection of vegetables in a timely manner to prevent the occurrence of freezing damage and low temperature diseases (such as gray mold, soft rot, and sclerotia)
.
Since January, the overall temperature has been higher by 4 to 6 degrees Celsius, rainfall by 20 to 50%, and sunshine duration by 20 to 50%, which is conducive to the overwintering and growth of crops
.
It is the Spring Festival.
Most workers return to their hometowns to celebrate the festival.
There is a shortage of personnel, and management measures are prone to inadequate management.
This leads to weak pest control and poor control effects during the production process, thereby increasing the prevalence of pests
.
The guidelines for the safe application of pesticides in vegetables during the Spring Festival are as follows: 1.
Current occurrence of pests and diseases 01 Vegetable diseases and freezing damage (open field): white rust 4%–32%; black rot disease 6%–25%, white spot disease about 1.
5%; freezing damage About 15%, the shade is heavier
.
Diseases and frost damage (protected areas): downy mildew is about 2.
5%, black rot is 0%-5.
5%, no frost damage is seen
.
No obvious disease was seen in the seedling stage
.
02 Cabbage disease and freezing damage (open field): about 30% of soft rot, sclerotinia disease and rotten plants 03 Cabbage disease and freezing damage (open field): soft rot and rotten plants about 35% disease and freezing damage (protected area): black rot Disease 0%–7% Pests (protected areas): occasionally the larvae and adults of Plutella xylostella
.
04 Radish disease and freezing damage (open field): black rot disease 4%-16%, occasionally rotten plant disease and freezing damage (protected area): black rot disease about 6% 05 Spinach disease and freezing damage (open field): freezing damage 15%-40 %, the shade is severe, the leaves are frostbite, wilted, and fall down
.
Diseases and freezing damage (protected areas): No obvious diseases and freezing damages were seen
.
06 Diseases and freezing damage of lettuce and lettuce (protected area): Sclerotinia sclerotia 2.
5%-4%
.
Sclerotinia sclerotiorum at seedling stage is about 0.
2%
.
07 Celery disease and frost damage (open field): 60% of soft rot and frost damage, yellow leaves, leaves fester, wilt, and fall down
.
After cooling, some retail households adopt small sheds for heat preservation
.
Diseases and freezing damage (protected areas): Gray mold is about 0.
5%
.
In addition, except for a few yellow leaves, no obvious diseases were seen
.
08 Broad bean disease and frost damage (open field): frost damage 20%-85%, severe shade, frostbite leaves, wilting black
.
09 Onion and garlic diseases (open field, protected field): all have yellow leaves, the open field is heavier, and there is no obvious disease
.
10 Freezing damage during the seedling stage of solanaceous fruit is 1%-5%, and no obvious disease is seen
.
Some cooperatives have been established
.
11 Underground pests sieve field haystacks and piled wastes, see individual cutworm larvae
.
SPRING FESTIVAL 2.
Scientific use of pesticides 01 Correctly identify diseases, pests and weeds, and apply them in a timely and symptomatic manner
.
Correctly identifying vegetable diseases, pests and weeds is a prerequisite for scientific and safe use of pesticides
.
02 The pesticide should be applied in an appropriate amount in strict accordance with the scope of use, method of use, recommended dosage, technical requirements and precautions on the pesticide label.
It is not allowed to expand the scope of use, increase the dosage or change the method of use
.
Green prevention and control technology is the first choice when preventing pests and diseases
.
03 Reasonably rotate and use pesticide varieties with different mechanisms of action
.
04 Pay attention to the safe harvest interval
.
Before agricultural products are harvested, the use of pesticides shall be stopped in accordance with the requirements of the safety interval
.
05 Prohibited pesticides must not be used
.
06 The application of pesticides must prevent pollution of nearby water sources, soil, etc.
, and protect the surrounding environment.
It is not allowed to discard pesticides, pesticide packages or clean pesticide application equipment in drinking water source protection areas or rivers
.
Pesticide packaging waste should be recycled to the designated recycling point
.
07 When applying pesticides, sprayers must take safety protections
.
When using pesticides, wear protective equipment, and do not eat or smoke
.
Wash hands, bathe, change clothes after application, and clean spray equipment
.
