Chamber, kill the pest of sugarcane: Must extinguish and prevent back service

The sugarcane borer control in general, sugarcane borer species 4 new brown top bar in particular is very difficult. The reason is the large sugarcane biomass, tall trees, loud, prolonged growth period, often intensive, growing thick, rationing years. Therefore, in addition to prioritizing control measures do not cause or causes less environmental pollution, little or no biological imbalance in nature, the use of the following measures are essential in control group sugarcane borer ...

It's the same measures as using fewer pests (U-Thong 1, F156, K90-54 ...); breeding and release the parasitic wasp species (red-eye Trichogramma wasp, Cotesia flavipes white cocoon bee, bee Tetrastichus sp, or springtails pliers Euborellia sp); healthy trees (fertilizer balance and reasonable irrigation, timely weeding, tending to plow good); visit our frequently to detect and destroy worms soon; Using pheromones traps, light traps ...

The above mentioned measures should be applied early, synchronized, regularly and continuously from prior to planting sugar cane until the cane harvesting and care of the original harvest. The effectiveness of the above measures are usually evident only after a long time applied on an area wide enough. This requires growers to be very tenacious, it brings new success.

However, due to the damage of sugarcane borer species first 4 brown outlined in Xining was alarming, deep into an epidemic arose, therefore, sugarcane farmers can not apply the measures mainly in favor of prevention as mentioned above. Instead, the need to apply chemical treatments or other special measures in accordance with specific harmful species of sugarcane borer first 4 bars of brown to stamp out, and above all to prevent as far as possible multi-state region spread out a particular sugarcane in the province, the nation and around the province in general, nor to translate back in later years.

Chemical methods will certainly cost more expensive and can not help being saved Fields deep heavy damage, but the effect to prevent spreading pests and significant restrictions on the source of deep residual copper fields spread to the next cane crop.

To do that, it should be conducted immediately following things: DARD and the sugar mills should jointly held immediately missions, the investigation team to the area of cane, making each field plot to survey , determine the scope and severity of the worm, and even the organization of conferences, seminars, workshops extension ... to disseminate information quickly about the sugarcane borer species first 4 bars brown. Also need guidance technicians, service personnel agriculture, the inspectors of the sugar mills and the farmers apply emergency measures in time to prevent the spread of harmful pests on a large scale, pressure application of the precautionary approach in the long term to control sugar cane pests not above flare up again in the following years.

After investigation, survey, conducted to classify each parcel under 2 Fields harmful levels: the level of harmful heavy slang rate of 10% and deep victims were spread all over the field; level minor damage ratio slang victims <10% and is in the form of deep outbreak.

For severely damaged field plots at the rate of 10% and the victim slang has spread deep across the field plots are (were in the peak epidemic to epidemic prepare setback), to the use of pesticides contains the active ingredient deltamethrin, Cypermethrin or Chlorantraniliprole to spray, the drug concentration in the water phase-out should be 0.1% if less than 50% of the worms caught investigation before spraying has entered the stage larvae age Last, chrysalis or pupa was neutered adult chemical weapons. And if that rate is higher than 50%, the drug concentrations required phase-out is 0.15% (as recommended by Thailand).

Should use insecticide sprays high pressure to spray in the early morning (5-6 hours) or evening (16-18 hours), focused on the spray deep outbreak (manifested by symptoms of sugarcane was dried tops, crops are more wormhole).

Because sugar cane grown, harvested about to take the motorcycle, it is difficult to go into each field plot that should detour around each plot to spray, forming a "soft belt", ranging from 15 - 20 meters around each field plot heavy infestations to prevent worms from spreading to the next field.

Absolutely no worker should wear wading into aerosol spray fields, such as very toxic to spray the riders, by the cane at this stage was big, reach high efficiency spray around adult breast height, foliage cane was closed and the spray will surely poison while breathe.

In those areas where conditions allow (cane has reached the minimum requirement of sugar processing, transporting favorable or acceptable plant collection), should be harvested as soon as possible to the field plots were serious pests, to "salvage" parts sugarcane production in the field, limiting losses, and eliminate pests quickly source hiding in sugarcane stalks.

Within 10 days of harvest, for lots zoned land can not burn leaves (due to the risk of fire spreading to the field next to it) may use the above pesticides mixed with water at a concentration of about 0.1% for injection into the original cane across the field plot aimed at annihilating source of refuge deep in the field to spread to the next case.

For field plots at a rate slightly damaged slang victims <10% and is deep in the outbreak period, each outbreak had a few dust or adjacent sugarcane leaf wilt symptoms on sugarcane variety wormhole, need for employees to carry a knife and holster along each cane, around the area of each field plot, find each worm outbreak (with adverse symptoms as described) to cut the harmful plant pests put the cover, collectors brought out, then bring destruction by soaking in ditches, pits, lime water tanks, hot water tanks, water tanks or bringing pesticides burning pile.

This work should be carried out continuously 3-4 times in 3 consecutive 4-week period in late September, early December 10.2014. This is however quite a lot of work and have to accept losing a sugarcane (due to cut) but it does not pollute the environment, the safety of workers, to ensure destroy a lot of depth.

A sugarcane borer was first 4 bars often contain harmful brown average several dozen small worm so if removed and destroyed by a sugar cane pests could save thousands of different sugarcane pests not later .

For sugarcane areas in other provinces, especially in the area of sugarcane cultivation conditions similar to the lowland cane Xining necessary to effect the investigation, survey and deep grasp right situation cane diseases in general, sugarcane borer first 4 lines in particular brown around the area planted to sugarcane. If you see a dangerous worm that began to appear in the field, though the rate is very low, it should be widely reported for sugarcane growers know, for timely prevention organization in a way similar to the field plots at a rate slightly damaged slang victims <10% and worm outbreaks are on this stage.

Practices harmful pest of sugarcane in Xining proved the effectiveness of the above measures. Fields are lots of regular visitation, timely detection and the process of destroying pests and diseases are caused by the time this little pest damage than no prevention field.

MARD, Tay Ninh province to consider funding immediately to the institutes and centers, the specialized agencies and the sugar mills in the province together, in depth research comprehensively on stemborers cane 4 new lines, to help the sugar industry in Tay Ninh province in particular and Vietnam in general to quickly set up and applied successfully integrated management process it effectively in the future.
