Due to steep rice roots, nutrient deficiency or pest , and sometimes there will be similar with herbicide injury symptoms , but through research and analysis , you can still determine whether they are herbicide injury .
From the amount of pesticide low pressure sprayer spraying periods and judgment
If application time after transplanting of rice l ~ 2d, rice case sensitive , sometimes injury. Administered high doses of individual pesticide products are also prone to injury.
Check fertilizer, soil conditions
Irrigation after the drug is too deep ( immersion growing point ) , easy to produce injury . Check whether due to improper fertilization , or administration no decomposition of organic manure, green manure or straw waterlogged field caused by improper growth of plants adverse symptoms appear .
Check pests
Rice thrips and rice food rootworm hazards rice plants will grow shorter , small clusters , tip section tubular roll becomes brown, fibrous roots short . Ordinary rice dwarf virus symptoms are mainly yellow leaves and withered volumes, dwarf plants , began to fade from the top tip , plaques appear broken , but the veins remain green , leaf green and yellow stripes often has the obvious .
Look around fruit tree sprayer spraying seedlings growing
After the normal green rice transplanting ( Li Miao ) , after application such as abnormal symptoms, and adjacent seedling quality with the same species of other plots seedlings grew normally , this may be caused by injury .

Suggestions to improve the pesticide market
For the current pesticide market several major problems, I propose the following recommendations to improve the domestic pesticide usage.
1. Pesticide safety training efforts to increase scientific, training dealers and farmers awareness of safe medication. The grassroots agricultural workers, dealers and farmers for safe and rational use of pesticides knowledge and technology information and training, the formation of a scientific and rational use of pesticides conscious atmosphere. Meanwhile, for the occurrence and control of pests of different crops during the timely organization of scientific and technological personnel to go to the grassroots and providing technical guidance to carry out pollution prevention technology training to enable farmers not only master the techniques of scientific medicine,sprayer but also fully aware of the ecological environment and pesticide contamination harm the health of people.
2. The establishment of safe use of pesticides demonstration fields, visually guide the farmers medication safety. In the demonstration venue, in strict accordance with technical regulations, timely and rational use of pesticides, with minimal dose for maximum control effect, so not only cost effective, but also protect the ecology.
3. Introduction of testing new pesticides, and actively promote the new pesticides. Strengthen the new pesticide testing, demonstration and promotion, screening efficiency, low toxicity, low-residue pesticides, bio-pesticides, to replace the highly toxic, high residue pesticides. Expand insecticidal lamps, sex attractant agent physical, biological technology area, and actively carry out ecological controlling pests and biological control techniques popularized.
4. To promote the introduction of new Equipments, improve the utilization of pesticides. Spraying machine must accelerate the upgrading of application techniques while actively making improvements, changing the traditional high-volume, low-capacity large weed sprayer spray droplets and fine droplet spray. Establishment of specialized defense team, promote motorized sprayer, improve control and reduce pesticide waste and pollution.
5 Strengthening pesticide residue monitoring, production of pollution-free agricultural products. Pesticide residue monitoring job is to protect people's health needs, is to improve the competitiveness of agricultural exports needs, but also the sustainable development of China's agricultural needs. Look perfect as soon as possible pesticide residue testing equipment, staffing, will monitor pesticide residues as a key task.
6. Strengthen market management of pesticides. Pesticide management departments should strengthen law enforcement efforts to rectify the pesticide market, and resolutely fight against counterfeit pesticides, pesticide labels failed to purify pesticide marketing channels for the safe use of farmland to create a favorable market environment. Punished for violations, improve pesticide production, management, legal awareness of users, crack down on illegal production, management, use of pesticides behavior, to prevent illegal pesticide production, management and use, as to create conditions for the safe and rational use of pesticides.

Remove stagnant water flower seedlings against pests
Flowers to resume production after the disaster, the following points should take timely measures:
After the storm, the timely removal of pots, planting ground water, avoid prolonged flooding lead to suffocation, yellow leaves, ethylene production, leaf wilt appear carved, falling and so on. Flooded the park can dig drainage ditches or machinery. The park blocks on poor drainage should be dug in the garden outside several storage pits, portable power sprayer will pit water discharge. Flat on the waterlogged depressions parks, fields should be cultivated itself into a permanent bar or table fields.
Floods, soil compaction due to prolonged water and the soil organisms, organic matter, etc., due to anaerobic respiration and fermentation, there lees flavor, it would seriously affect root growth. Should be promptly removed weeds, and 1-2 times plowing (plowing depth should not be too deep, usually 15-20cm appropriate), to release excess moisture in soil, improve soil aeration prevents root suffocation.
Prolonged flooding, soil moisture is too large, easily lead to the occurrence of disease stems and roots, so the post-disaster pest control is particularly important. Such as disaster prone to downy mildew, gray mold, rot, disease, etc., should be strengthened in order to avoid the spread of disease prevention and control. Especially in the facility after breaking soil fertility in different environments, more prone to sunburn, blight, black spot disease, such as anthrax. Should be taken to branches painted white (to prevent sunburn and other stem diseases infection), trigger sprayer sprayed protective agents, such as foliar spray once thiophanate-methyl, carbendazim, chlorothalonil, so as to ensure that branches and leaves intact, and promote photosynthesis.

Vegetable pests spraying techniques
Wide variety of vegetable pests, but can be summarized as suck juices, fresh leafy and boring classes three categories. Each type of pest habits are not the same. According to their character and individuality as well as the growth characteristics of the host, targeted spraying control, make direct contact with the parasite agents, achieve better control effect.
1, spraying techniques and pest infestation habits and living habits are closely related to aphids suck juices and some leaf-eating pests concentrated in the dorsal and twigs parasitic infestation, it should be a "little circle" approach to spraying, namely spray nozzles garden sprayers spray plant leaves bear the first lap, and then spray it buckle in the tender head, thus making contact with all pharmaceutical plants and parasites, to receive better control effect. Spodoptera exigua, beet armyworm larvae daytime hiding old phenomenon, so the growing season spraying control such pests, preferably in the evening. Borer pests cabbage webworm spraying time must be at the peak of hatching.
2, spraying technology but also with the growth characteristics of the host is closely related to the summer cowpea flowering time around in the morning 7:30-10:30, after all this time its petals closed. Cowpea early instar larvae borer infestation dispersed or concentrated, tree sprayer spraying at 9:00 in front as well, so that we can make more fully exposed to the parasite agents, or missed opportunities. Kale leaves covered with a layer of wax, with a biological insecticide Bt Pieris rapae, often adding 0.1% in liquid detergent, the purpose is to reduce the surface tension of the liquid evenly distributed in the leaves, improve control effect.

Paraquat and fine grasses g can not be ignored
Paraquat is a herbicide quick Destuctive tag , can be used in no-till corn or late adult weeding weeds . Wheat harvest , without plowing , direct sowing corn per acre with 15% pre-emergence agent
265 ~ 400 ml, watered 20-30 kg back pack sprayer spray. Do not let 24 hours after spraying spraying livestock into the area . People wrongly poisoning should immediately induce vomiting and sent to hospital for treatment .
Quizalofop ( fine grasses g )
( A ) the cause of the injury . Stem and leaf processing corn Quizalofop sensitive , mistakenly applied or adjacent land spraying, spray drift to corn plants will produce injury.
( Two ) phytotoxicity symptoms. With herbicides stems, leaves processed , beginning chlorotic leaf base from the heart , leaves appear water-soaked spots, yellow purple and gradually dry up . Base necrosis , gently pull that one off from the leaf base , broken occurring after soaked brown . Seedlings dead about two weeks .
( Three ) injury prevention and mitigation measures . Quizalofop not be used for corn . Neighboring land administered Quizalofop should allow enough distance isolation belt, pay attention to wind direction and speed when spraying , to prevent the liquid float moves cornfield. Once water pressure sprayer spraying serious and should be promptly replant.

Rice pesticide use but also can be to
Dressing method .
Dressing method is the pharmaceutical and seed evenly mixed together , so that the seed surface covered with a layer of powder or emulsion , for the control of soil pests , insects and seed-borne diseases seedling method of application . This method is suitable for dusts, wettable powders, emulsifiable concentrates , liquid dosage forms , with high efficiency, good control effect , no effect on the natural enemies , without water restrictions, etc. . In powder dressing , can be placed on pesticides and seed dressing , or other apparatus within the uniform mixing . With wettable powders, emulsifiable concentrates or aqueous dressing should press with a good proportion of dilution liquid, then spray the liquid spray to the seed , while spraying edge mix . After dressing , preferably 2 to 3 days pile boring , so that agents are sufficiently adsorbed seeds , pesticides due performance in order to play .
Dipping method .
Dipping method is to pesticides diluted with water , put the seeds or seedlings soaked in liquid , that the seed and seedling absorption and adhesion some agents, for the control of pests and diseases , and promote seedling root bud development . This method is suitable for cream, liquid, wettable powder formulations , with flower workers less seedling effect, with less pesticides and other advantages.
Bait method .
Bait method is to use bait ( various grains , bran, sugar , potatoes, cooking oil residue , etc. ) and their counterparts with stomach toxicity pesticide mixing bait , scattered in the fields, for the control of soil pests , rodents application methods .
This method is suitable for dusts, wettable powders, emulsifiable concentrates , liquid dosage forms . When in use, should be selected palatable food prepared fresh bait , and according to the feeding habits of insects and rodents , on a sunny day early in the morning or evening Bait . Adding crop seedling baits usually in the evenings or rain , fruit tree sprayer the effect is better.
Fumigation .
Fumigation method is the use of fumigants or easily volatile agents produced a sterilizing gas to insecticide spraying method . This method is suitable for warehouses, greenhouses , soil or crop lush place , with anti -efficient, fast-acting , etc., but the operation is technically demanding, spraying conditions are more stringent . Fumigation in the warehouse , to ensure a good seal , should be adequately ventilated after fumigation , the gas escapes . Soil fumigation , the effect can be closed with water , i.e. in the treated soil surface layer of water spray , can delay the fumigant to escape. Between the lines in the crop fumigation , should choose dense crops and appropriate temperature conditions , a sunny day .
Fumigation method .
Fumigation method is to smoke or ignite fuming fuming original drug to direct heat application methods of pest control . This method is suitable for use in a closed environment ( such as warehouses ,manual sprayer greenhouses ) or canopy high places, such as the growth of field crops later use . Pharmaceutical form of smoke gas diffusion have better penetration and proper settlement of space to stay longer, but not overly floating drift , so as to achieve good results.
