vy Device and method for treating palm trees affected by the red palm weevil using fumigation

A device and method for treatment of red palm weevils using fumigation Full description Background of the invention red 0 and many types of palm trees have been found in many countries of the world and cause great economic losses m in Qatif and have spread since then 197897 the discovery of the first infection with it in the Kingdom of Saudi Arabia in the year 0 then in all regions of the Kingdom and the number has increased infected palm trees during the past three years. Large, despite the existence of control programs for the red palm weevil implemented by the Ministry of Environment, Water and Agriculture. The use of (JE) in the previous decades. Many methods of resistance to the insect have been tried, such as DIA, light and pheromone traps, as well as the removal, burial, chopping or burning of infected palms, as well as Scraping the affected areas until reaching the healthy tissue or injecting several types of pesticides around the affected area 0 or fumigation using aluminum phosphate pills at the entrance to the affected area.So far many biological control methods have also been tried. The success rates of these methods have varied, and the low success rate of 701009 is attributed to a way to eradicate this insect in the affected palm trees, due to the depth of the insect in the heart of the trunk and the difficulty of identifying the areas of infection, and then the difficulty of delivering the appropriate pesticide to all These insects are inside the affected palm trees. 0 The earliest cases of industrial technology related to the subject of the invention are document (a) the patent of Muhammad Al-Jaber and those with him and the deal for the inventor 7007 March American YY No. 2970/851, 9 dated Belonging to the inventor (Yoo Yoo) February YY dated + ,1,970,777 (b) US Patent No. .

electromagnetic waves to two panels surrounding the palm tree, with the aim of eliminating the red palm weevil; Lad Document (c) talks about a method for eliminating insects in general that infect trees by using a plastic film that performs the function of a barrier that surrounds the tree and prevents agricultural pests such as insects from it.

© Whereas the current invention overcomes the problem of penetration of insects into the palm tree, especially the red palm weevil insect and its deepening in the heart of the tree trunk. tree through injections or making tunnels inside its trunk.

0 The present invention aims to deliver a suitable pesticide with sufficient concentration and sufficient period for all stages of the insect in the affected palm tree without the need to damage the trunk of the palm tree through injection processes or making tunnels using electric or manual drills or scraping the affected tissues. The insect needs fresh air to provide oxygen to survive. The air reaches it from outside the palm tree through the tunnels that it digs, which usually extend from the end of the excavation tunnel, where the insect resides, to the outer perimeter of the palm tree.

Vo is the area of initiation of injury where air enters. Air has been used to try to deliver aluminum phosphate pesticide gas decades ago to try to eliminate the insect in the affected palms by placing pesticide grains at the entrance to the infection area or inside tunnels dug for this purpose, and this method succeeded only to a limited extent. This can be attributed to the lack of pesticide gas remaining in the vicinity of the palm tree for a sufficient time to ensure that the pesticide reaches sufficient concentration and sufficient duration to all insects in the depth of the affected palm tree.

0 General description of the invention The present invention is a device consisting of an air insulating cover that is placed around the trunk of the palm tree starting from the surface of the earth and at a height (iY), or to the beginning of the vegetative pail (if the palm tree is shorter than that) or over the injury area and for a distance Fe), Yo extends below and 7©5.1 meters above the injury area if the injury area is far from the surface of the earth and is sealed from the bottom and the top through devices

An innovative tensioner that prevents the pesticide from leaking out. These devices contain a belt that is fixed on the outer cover. A high-density sponge is placed between the cover and the trunk of the palm tree to seal the gap between the cover and the trunk of the palm tree. The belt is tightened by a mechanical mechanism to ensure that the air outlets are closed to isolate the surroundings of the palm tree from air. And in the event that the palm tree is short, it is limited to sealing with Jel and burying the lower part with soil in a trench 10 cm deep, 10 cm from the trunk of the palm. The device contains an opening that can be opened and closed.

To place aluminum phosphate pesticide pills or to pump pesticide gas inside this cover on the perimeter of a trunk. All of this aims to maintain a high concentration of the pesticide in the vicinity of the palm tree and to prevent its leakage to the outside throughout the treatment period to ensure that the pesticide reaches through the tunnels to all stages of the insect inside the palm tree.

Co so that the cover (1) is wrapped around the trunk of the palm tree and it is closed from the top and bottom through a tension belt, and phosphate pesticide grains (o£) are inserted at the top and bottom (7) and the belt is tightened with an aluminum automatic tensioning tool or pesticide gas is pumped from the hole (7) around the perimeter of the trunk and close it tightly; and the sponge (0) is placed between the tension belt and the palm to seal the void.

In order to ensure that the aluminum phosphate gas remains in the vicinity of the palm tree for a long time, during which the pesticide reaches all insects in the excavation tunnels, this invention was invented, through which the infected area and the following areas of the trunk of the palm tree are covered with an extension of 1.50 meters with an air-insulating sala or from Ground level until the beginning of vegetative growth if the palm tree is shorter than that. All ports that allow air to escape are sealed using an innovative tensioning device that prevents pesticide gas from leaking from the upper and lower ends of the device.

0 And then placing the pills of aluminum phosphate pesticide between the air insulator and the trunk of the palm tree and keeping the affected palm tree under treatment for a period of 01-© days during which the high concentration of andl through the drilling tunnels will reach the palm weevil insects. Preliminary experiments have shown the success of this method in eliminating all stages of the insect in all infected palms to which the invention was applied. Several field experiments have been carried out to determine the lowest dose of the pesticide and the shortest treatment period that succeeds in eradicating the disease

No all stages of the insect in the infected horse. Experiments were carried out on more than 600 infected palm trees, and the injuries ranged from superficial to severe injuries, and the results of the experiments proved the elimination of all stages of the insect inside the affected palm tree, which was treated in this way and the device. The safety of this method of use has been proven to be successful in keeping the gas inside the palm tree at therapeutic concentrations and for a sufficient period of time to treat

0 stages of the weevil, which is an unprecedented success in the use of fumigants in the treatment of the palm weevil
