Along with the agricultural supply side structural reform, continuously adjust and optimize the structure of planting industry, in 2016 the province’s grain crop acreage continues to increase, to further improve the level of quality varieties, rapeseed, cotton acreage continued to shrink, vegetables and fruits, grains and the efficient agriculture planting area has increased, the advantage of planting areas, industries, high quality varieties were cluster the use of pesticides, the variety and amount of change.
According to the analysis of the occurrence tendency of crop planting structure in Jiangsu province and important crop pests, the province is expected in 2017 demand the use of pesticides and the same in 2016 the actual amount of pesticide. High efficiency, low toxicity and low residue amount of chemical pesticides and biological pesticides will further increase the dosage of insecticide, fungicide dosage of flat flat, slightly reduced, herbicide dosage will increase slightly.
The use of pesticides in 2016
In 2016 the province’s total pesticide use is about 77000 tons, 1100 tons less than the actual amount of 2015, down 1.4%. Its main features:
1.1 pesticides continue to reduce
In 2016 the rice pest was in a moderate, particularly two migratory pests is light to medium, the occurrence degree of light in 2015. According to the pest situation, carefully organized around the prevention, pay attention to scientific medicine, promotion of green control technology, using physical prevention and control measures, optimization of pesticide combination optimization and efficient low toxicity and residue of chemical pesticides and biological pesticide, promotion of Pymetrozine, nitenpyram, diamide with high efficiency and low toxicity pesticides, effective control of the pests, and reduce the the use of pesticides.
1.2 fungicide dosage increased slightly
2016 wheat scab, and occurrence of rice sheath blight on rice blast occurred on the medium. According to the disease condition and scientific medicine, around the prevention and effective control of the disease. At the same time as the government procurement yipensanfang pesticide, effectively expanding the use area, coupled with the appropriate increase of Mu dosage, fungicide and dosage increased slightly.
1.3 new herbicide dosage went
There is a perennial weeds in rice fields on 2016, the occurrence area increased slightly in direct seeding rice weedy rice, thousands of gold and weeds weed control area increased demand. But because of too much rain in some areas, paddy not suitable period of medication, thus reducing the five fluorosulfonyl acetochlor and Cyhalofop butyl, five fluorine? Cyhalofop, Metamifop and other new herbicide dosage, leading to reduced the amount of herbicide use.
1.4 high efficiency and low toxicity pesticide residue application increased the proportion of
According to statistics, in 2016 the main crops on high efficiency and low toxicity pesticide use area accounted for 77.2%, compared with 74.2% in 2015 increased by 3 percentage points, especially in food crops with high efficiency and low toxicity pesticide use accounted for the high area. According to the 906 farmers (planting large family farms, professional service organizations) in rice field investigation, pesticide use, according to the amount of goods, micro toxic pesticides accounted for 5.56%, accounting for 84.77%, accounting for 9.55% of low toxicity and high toxic pesticide poisoning accounted for 0.12%, low micro toxic pesticides accounted for 90.33% of the total. In the wheat field pesticide use, according to the amount of goods, micro toxic pesticides accounted for 5.33%, accounting for 89.32%, accounting for 4.46% of low toxicity and high toxic pesticide poisoning accounted for 0.89%, low micro toxic pesticides accounted for 94.65% of the total.
1.5 the use of pesticides to further optimize the structure
The use of pesticides and the amount and structure of plant diseases and insect pests occurrence are closely related. According to statistics, in 2016 by the use of pesticide commodity meter, insecticide and acaricide, fungicides accounted for 35.58% accounted for 37.02%, accounted for 26.65% of the herbicide and plant growth regulator rodenticide accounted for 0.47%, accounted for 0.28%. All kinds of crops on the use of pesticides are not the same structure, pesticide use in rice field in 2016 (by commodity volume), insecticide fungicide accounted for 41.66%, accounted for 40.67%, accounted for 17.66% of the herbicide and plant growth regulator accounted for 0.01%; the amount of varieties from large to small is as follows: Tricyclazole, abamectin, butachlor, isoprothiolane Pretilachlor, Pymetrozine, and diazinon, emamectin benzoate, validamycin A, thifluzamide etc.. In the wheat field in the use of pesticides (by commodity volume), insecticide fungicide accounted for 16.76%, accounted for 54.11%, accounted for 29.12% of the herbicide and plant growth regulator accounted for 0.01%; the amount of varieties from large to small is as follows: carbendazim, isoproturon, three Triadimefon, fluroxypr mepthyl, thiram and fenoxaprop-p-ethyl, phoxim, Clodinafop propargyl, Pymetrozine JS399-19, tebuconazole, etc..
2017 pesticide consumption demand forecast
The total amount of pesticide demand in 2017 is expected to be 76 thousand and 500 tons (the amount of goods, the same below), down 500 tons more than in 2016. Expected miticide demand is 27 thousand and 500 tons, accounting for 35.9%; fungicide demand is 28 thousand tons, accounting for 36.6%; herbicide demand of 19 thousand and 500 tons, accounting for 25.5%; the other (plant growth regulator, raticide) demand of 1 thousand and 500 tons, accounting for 2%. In the use of pesticides, high efficiency and low toxicity pesticide residue and biological pesticide application proportion will further increase, the amount of highly toxic pesticides will continue to reduce. It is the main basis for the forecast:
2.1 crop distribution is relatively stable
With the adjustment of planting structure optimization, the main crops cultivated area tends to be stable. 2017 is expected to grain acreage stable at 80 million acres, and in 2016 was flat slightly reduced, due to the benefit of planting and last winter rain effect, summer grain acreage decreased slightly; vegetables and fruits, especially the grains and agriculture because the benefit is relatively good, the area will increase slightly; rapeseed, cotton acreage further reduced, but Yajian little space.
The more severe situation occurred 2.2 pests
According to the pest occurrence base, species distribution, meteorological factors and other related factors in the occurrence and comprehensive analysis of the situation, is expected in 2017 of main diseases and insect pests of wheat and rice crops and still place emphasis, pest will rice in 2016 (one year weight lighter history).
2.3 pesticide use reduction continue to force
In order to implement the spirit of the 2017 central document, vigorously promote green agricultural production mode, the implementation of Jiangsu province “two minus six for three” special action and the relevant requirements of the Ministry of agriculture in 2020 to pesticide use zero growth action “, the country will intensify its efforts to carry out agricultural enterprises to build demonstration base, promotion of green control technology and the specialized anti rule fusion, effectively control and reduce the dosage of chemical pesticide. Protected areas of Taihu chemical pesticide use total by 2020 compared with 2015 cuts of more than 20%, South of Jiangsu is less than 5%, the Soviet Union in the reduction of about 1%, the rest of the zero growth.
2.4 high efficiency and low toxicity pesticide residue application area increased
In 2017, the province will continue to high efficiency and low toxicity pesticide residue included in the application area proportion of basic agricultural modernization evaluation system of assessment indicators, all will take effective measures to increase efforts to promote the high efficiency and low toxicity pesticide residue, application area proportion will rise. At the same time, along with the agricultural supply side structural reform, the implementation of green production, people put forward higher requirements on the quality of agricultural products and food safety, without the use of pollution-free agricultural products, green food production base of pesticides made clear requirements, high efficiency and low toxicity, low residue pesticides concern.
